Combobox

Comboboxes are the foundation of accessible autocompletes and command palettes for your app, complete with robust support for keyboard navigation.

To get started, install Headless UI via npm:

npm install @headlessui/react

Comboboxes are built using the Combobox, ComboboxInput, ComboboxButton, ComboboxOptions, and ComboboxOption components.

You are completely in charge of how you filter the results, whether it be with a fuzzy search library client-side or by making server-side requests to an API. In this example we will keep the logic simple for demo purposes.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

Headless UI keeps track of a lot of state about each component, like which combobox option is currently selected, whether a popover is open or closed, or which item in a menu is currently focused via the keyboard.

But because the components are headless and completely unstyled out of the box, you can't see this information in your UI until you provide the styles you want for each state yourself.

The easiest way to style the different states of a Headless UI component is using the data-* attributes that each component exposes.

For example, the ComboboxOption component exposes a data-focus attribute, which tells you if the option is currently focused via the mouse or keyboard, and a data-selected attribute, which tells you if that option matches the current value of the Combobox.

<!-- Rendered `ComboboxOptions` -->
<div data-open>
  <div>Wade Cooper</div>
  <div data-focus data-selected>Arlene Mccoy</div>
  <div>Devon Webb</div>
</div>

Use the CSS attribute selector to conditionally apply styles based on the presence of these data attributes. If you're using Tailwind CSS, the data attribute modifier makes this easy:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { CheckIcon } from '@heroicons/react/20/solid'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (

          <ComboboxOption key={person.id} value={person} className="group flex gap-2 bg-white data-focus:bg-blue-100">
            <CheckIcon className="invisible size-5 group-data-selected:visible" />
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

See the component API for a list of all the available data attributes.

Each component also exposes information about its current state via render props that you can use to conditionally apply different styles or render different content.

For example, the ComboboxOption component exposes a focus state, which tells you if the option is currently focused via the mouse or keyboard, and a selected state, which tells you if that option matches the current value of the Combobox.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { CheckIcon } from '@heroicons/react/20/solid'
import clsx from 'clsx'
import { Fragment, useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (

          <ComboboxOption as={Fragment} key={person.id} value={person} className="data-focus:bg-blue-100">
            {({ focus, selected }) => (
              <div className={clsx('group flex gap-2', focus && 'bg-blue-100')}>
                {selected && <CheckIcon className="size-5" />}
                {person.name}
              </div>
            )}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

See the component API for a list of all the available render props.

Wrap a Label and Combobox with the Field component to automatically associate them using a generated ID:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions, Field, Label } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (

    <Field>
      <Label>Assignee:</Label>
      <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
        <ComboboxInput displayValue={(person) => person?.name} onChange={(event) => setQuery(event.target.value)} />
        <ComboboxOptions anchor="bottom" className="border empty:invisible">
          {filteredPeople.map((person) => (
            <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
              {person.name}
            </ComboboxOption>
          ))}
        </ComboboxOptions>
      </Combobox>

    </Field>
  )
}

Use the Description component within a Field to automatically associate it with a Combobox using the aria-describedby attribute:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions, Description, Field, Label } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (

    <Field>
      <Label>Assignee:</Label>

      <Description>This person will have full access to this project.</Description>
      <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
        <ComboboxInput displayValue={(person) => person?.name} onChange={(event) => setQuery(event.target.value)} />
        <ComboboxOptions anchor="bottom" className="border empty:invisible">
          {filteredPeople.map((person) => (
            <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
              {person.name}
            </ComboboxOption>
          ))}
        </ComboboxOptions>
      </Combobox>

    </Field>
  )
}

Add the disabled prop to the Field component to disable a Combobox and its associated Label and Description:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions, Field, Label } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (

    <Field disabled>
      <Label>Assignee:</Label>
      <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
        <ComboboxInput displayValue={(person) => person?.name} onChange={(event) => setQuery(event.target.value)} />
        <ComboboxOptions anchor="bottom" className="border empty:invisible">
          {filteredPeople.map((person) => (
            <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
              {person.name}
            </ComboboxOption>
          ))}
        </ComboboxOptions>
      </Combobox>
    </Field>
  )
}

You can also disable a combobox outside of a Field by adding the disabled prop directly to the Combobox itself.

Use the disabled prop to disable a ComboboxOption and prevent it from being selected:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds', available: true },
  { id: 2, name: 'Kenton Towne', available: true },
  { id: 3, name: 'Therese Wunsch', available: true },

  { id: 4, name: 'Benedict Kessler', available: false },
  { id: 5, name: 'Katelyn Rohan', available: true },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption
            key={person.id}
            value={person}

            disabled={!person.available}
            className="data-disabled:opacity-50 data-focus:bg-blue-100"
          >
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

You can allow users to enter their own value that doesn't exist in the list by including a dynamic ComboboxOption based on the query value.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">

        {query.length > 0 && (
          <ComboboxOption value={{ id: null, name: query }} className="data-focus:bg-blue-100">
            Create <span className="font-bold">"{query}"</span>
          </ComboboxOption>
        )}
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

If you add the name prop to your Combobox, a hidden input element will be rendered and kept in sync with the combobox state.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <form action="/projects/1/assignee" method="post">

      <Combobox name="assignee" value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
        <ComboboxInput
          aria-label="Assignee"
          displayValue={(person) => person?.name}
          onChange={(event) => setQuery(event.target.value)}
        />
        <ComboboxOptions anchor="bottom" className="border empty:invisible">
          {filteredPeople.map((person) => (
            <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
              {person.name}
            </ComboboxOption>
          ))}
        </ComboboxOptions>
      </Combobox>
      <button>Submit</button>
    </form>
  )
}

This lets you use a combobox inside a native HTML <form> and make traditional form submissions as if your combobox was a native HTML form control.

Basic values like strings will be rendered as a single hidden input containing that value, but complex values like objects will be encoded into multiple inputs using a square bracket notation for the names:

<!-- Rendered hidden inputs -->
<input type="hidden" name="assignee[id]" value="1" />
<input type="hidden" name="assignee[name]" value="Durward Reynolds" />

If you omit the value prop, Headless UI will track its state internally for you, allowing you to use it as an uncontrolled component.

When uncontrolled, use the defaultValue prop to provide an initial value to the Combobox.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <form action="/projects/1/assignee" method="post">

      <Combobox name="assignee" defaultValue={people[0]} onClose={() => setQuery('')}>
        <ComboboxInput
          aria-label="Assignee"
          displayValue={(person) => person?.name}
          onChange={(event) => setQuery(event.target.value)}
        />
        <ComboboxOptions anchor="bottom" className="border empty:invisible">
          {filteredPeople.map((person) => (
            <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
              {person.name}
            </ComboboxOption>
          ))}
        </ComboboxOptions>
      </Combobox>
      <button>Submit</button>
    </form>
  )
}

This can simplify your code when using the combobox with HTML forms or with form APIs that collect their state using FormData instead of tracking it using React state.

Any onChange prop you provide will still be called when the component's value changes in case you need to run any side effects, but you won't need to use it to track the component's state yourself.

Add the anchor prop to the ComboboxOptions to automatically position the dropdown relative to the ComboboxInput:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />

      <ComboboxOptions anchor="bottom start" className="border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

Use the values top, right, bottom, or left to center the dropdown along the appropriate edge, or combine it with start or end to align the dropdown to a specific corner, such as top start or bottom end.

To control the gap between the input and the dropdown, use the --anchor-gap CSS variable:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />

      <ComboboxOptions
        anchor="bottom start"
        className="border [--anchor-gap:4px] empty:invisible sm:[--anchor-gap:8px]"
      >
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

Additionally, you can use --anchor-offset to control the distance that the dropdown should be nudged from its original position, and --anchor-padding to control the minimum space that should exist between the dropdown and the viewport.

The anchor prop also supports an object API that allows you to control the gap, offset, and padding values using JavaScript:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />

      <ComboboxOptions anchor={{ to: 'bottom start', gap: '4px' }} className="border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

See the ComboboxOptions API for more information about these options.

The ComboboxOptions dropdown has no width set by default, but you can add one using CSS:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />

      <ComboboxOptions anchor="bottom" className="w-52 border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

If you'd like the dropdown width to match the ComboboxInput or ComboboxButton widths, use the --input-width and --button-width CSS variables that are exposed on the ComboboxOptions element:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />

      <ComboboxOptions anchor="bottom" className="w-(--input-width) border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

To animate the opening and closing of the combobox panel, add the transition prop to the ComboboxOptions component and then use CSS to style the different stages of the transition:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions
        anchor="bottom"

        transition
        className="origin-top border transition duration-200 ease-out empty:invisible data-closed:scale-95 data-closed:opacity-0"
      >
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

Internally, the transition prop is implemented in the exact same way as the Transition component. See the Transition documentation to learn more.

Headless UI also composes well with other animation libraries in the React ecosystem like Framer Motion and React Spring. You just need to expose some state to those libraries.

For example, to animate the combobox with Framer Motion, add the static prop to the ComboboxOptions component and then conditionally render it based on the open render prop:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { AnimatePresence, motion } from 'framer-motion'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson}>

      {({ open }) => (
        <>
          <ComboboxInput
            aria-label="Assignee"
            displayValue={(person) => person?.name}
            onChange={(event) => setQuery(event.target.value)}
          />
          <AnimatePresence>

            {open && (
              <ComboboxOptions

                static
                as={motion.div}
                initial={{ opacity: 0, scale: 0.95 }}
                animate={{ opacity: 1, scale: 1 }}
                exit={{ opacity: 0, scale: 0.95 }}
                anchor="bottom"
                className="origin-top border empty:invisible"
                onAnimationComplete={() => setQuery('')}
              >
                {filteredPeople.map((person) => (
                  <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
                    {person.name}
                  </ComboboxOption>
                ))}
              </ComboboxOptions>

            )}
          </AnimatePresence>
        </>

      )}
    </Combobox>
  )
}

Unlike native HTML form controls, which only allow you to provide strings as values, Headless UI supports binding complex objects as well.

When binding objects, make sure to set the displayValue on your ComboboxInput so that a string representation of the selected option can be rendered in the input:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'


const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (

    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"

        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">

            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

When binding objects as values, it's important to make sure that you use the same instance of the object as both the value of the Combobox as well as the corresponding ComboboxOption, otherwise they will fail to be equal and cause the combobox to behave incorrectly.

To make it easier to work with different instances of the same object, you can use the by prop to compare the objects by a particular field instead of comparing object identity.

When you pass an object to the value prop, by will default to id when present, but you can set it to any field you like:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const departments = [
  { name: 'Marketing', contact: 'Durward Reynolds' },
  { name: 'HR', contact: 'Kenton Towne' },
  { name: 'Sales', contact: 'Therese Wunsch' },
  { name: 'Finance', contact: 'Benedict Kessler' },
  { name: 'Customer service', contact: 'Katelyn Rohan' },
]


function DepartmentPicker({ selectedDepartment, onChange }) {
  const [query, setQuery] = useState('')

  const filteredDepartments =
    query === ''
      ? departments
      : departments.filter((department) => {
          return department.name.toLowerCase().includes(query.toLowerCase())
        })

  return (

    <Combobox value={selectedDepartment} by="name" onChange={onChange} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Department"
        displayValue={(department) => department?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredDepartments.map((department) => (
          <ComboboxOption key={department.id} value={department} className="data-focus:bg-blue-100">
            {department.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

You can also pass your own comparison function to the by prop if you'd like complete control over how objects are compared:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const departments = [
  { id: 1, name: 'Marketing', contact: 'Durward Reynolds' },
  { id: 2, name: 'HR', contact: 'Kenton Towne' },
  { id: 3, name: 'Sales', contact: 'Therese Wunsch' },
  { id: 4, name: 'Finance', contact: 'Benedict Kessler' },
  { id: 5, name: 'Customer service', contact: 'Katelyn Rohan' },
]


function compareDepartments(a, b) {
  return a.name.toLowerCase() === b.name.toLowerCase()
}

function DepartmentPicker({ selectedDepartment, onChange }) {
  const [query, setQuery] = useState('')

  const filteredDepartments =
    query === ''
      ? departments
      : departments.filter((department) => {
          return department.name.toLowerCase().includes(query.toLowerCase())
        })

  return (

    <Combobox value={selectedDepartment} by={compareDepartments} onChange={onChange} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Department"
        displayValue={(department) => department?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredDepartments.map((department) => (
          <ComboboxOption key={department.id} value={department} className="data-focus:bg-blue-100">
            {department.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

While it's very common to bind objects as values, you can also provide simple string values.

When doing this you can omit the displayValue prop from the ComboboxInput.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'


const people = ['Durward Reynolds', 'Kenton Towne', 'Therese Wunsch', 'Benedict Kessler', 'Katelyn Rohan']

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput aria-label="Assignee" onChange={(event) => setQuery(event.target.value)} />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (

          <ComboboxOption key={person} value={person} className="data-focus:bg-blue-100">
            {person}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

To allow selecting multiple values in your combobox, use the multiple prop and pass an array to value instead of a single option.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {

  const [selectedPeople, setSelectedPeople] = useState([people[0], people[1]])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (

    <Combobox multiple value={selectedPeople} onChange={setSelectedPeople} onClose={() => setQuery('')}>
      {selectedPeople.length > 0 && (
        <ul>
          {selectedPeople.map((person) => (
            <li key={person.id}>{person.name}</li>
          ))}
        </ul>
      )}
      <ComboboxInput aria-label="Assignees" onChange={(event) => setQuery(event.target.value)} />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

Your onChange handler will be called with an array containing all selected options any time an option is added or removed.

Use the immediate prop to immediately open the combobox options when the combobox input is focused.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (

    <Combobox immediate value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

By default, the Combobox and its subcomponents each render a default element that is sensible for that component.

For example, ComboboxInput renders an input, ComboboxButton renders a button, ComboboxOptions renders a div, and ComboboxOption renders a div. By contrast, Combobox does not render an element, and instead renders its children directly.

Use the as prop to render the component as a different element or as your own custom component, making sure your custom components forward refs so that Headless UI can wire things up correctly.

import { Combobox, ComboboxButton, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { forwardRef, useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]


let MyCustomButton = forwardRef(function (props, ref) {
  return <button className="..." ref={ref} {...props} />
})

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (

    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxButton as={MyCustomButton}>Open</ComboboxButton>

      <ComboboxOptions as="ul" anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (

          <ComboboxOption as="li" key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

To tell an element to render its children directly with no wrapper element, use a Fragment.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { Fragment, useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>
      <ComboboxInput

        as={Fragment}
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      >
        <input />
      </ComboboxInput>
      <ComboboxOptions anchor="bottom" className="border empty:invisible">
        {filteredPeople.map((person) => (
          <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        ))}
      </ComboboxOptions>
    </Combobox>
  )
}

Depending on what you're building it can sometimes make sense to render additional information about the active option outside of the ComboboxOptions. For example, a preview of the active option within the context of a command palette. In these situations you can read the activeOption render prop argument to access this information.

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox value={selectedPerson} onChange={setSelectedPerson} onClose={() => setQuery('')}>

      {({ activeOption }) => (
        <>
          <ComboboxInput
            aria-label="Assignee"
            displayValue={(person) => person?.name}
            onChange={(event) => setQuery(event.target.value)}
          />
          <ComboboxOptions anchor="bottom" className="border empty:invisible">
            {filteredPeople.map((person) => (
              <ComboboxOption key={person.id} value={person} className="data-focus:bg-blue-100">
                {person.name}
              </ComboboxOption>
            ))}
          </ComboboxOptions>

          {activeOption && <div>The currently focused user is: {activeOption.name}</div>}
        </>
      )}
    </Combobox>
  )
}

The activeOption will be the value of the currently focused ComboboxOption.

By default the Combobox renders all its options into the DOM. While this is a good default, this can cause performance issues when given a really large number of options. For these situations we provide a virtual scrolling API.

To enable virtual scrolling, provide a list of options to the Combobox via the virtual.options prop, as well as a render prop to the ComboboxOptions, which acts as a template for each option:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds' },
  { id: 2, name: 'Kenton Towne' },
  { id: 3, name: 'Therese Wunsch' },
  { id: 4, name: 'Benedict Kessler' },
  { id: 5, name: 'Katelyn Rohan' },
  // +1000 more people
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox
      value={selectedPerson}

      virtual={{ options: filteredPeople }}
      onChange={setSelectedPerson}
      onClose={() => setQuery('')}
    >
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="w-(--input-width) border empty:invisible">

        {({ option: person }) => (
          <ComboboxOption value={person} className="data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        )}
      </ComboboxOptions>
    </Combobox>
  )
}

To specify whether a given option is disabled, provide a callback to the virtual.disabled prop:

import { Combobox, ComboboxInput, ComboboxOption, ComboboxOptions } from '@headlessui/react'
import { useState } from 'react'

const people = [
  { id: 1, name: 'Durward Reynolds', available: true },
  { id: 2, name: 'Kenton Towne', available: true },
  { id: 3, name: 'Therese Wunsch', available: true },

  { id: 4, name: 'Benedict Kessler', available: false },
  { id: 5, name: 'Katelyn Rohan', available: true },
  // +1000 more people
]

function Example() {
  const [selectedPerson, setSelectedPerson] = useState(people[0])
  const [query, setQuery] = useState('')

  const filteredPeople =
    query === ''
      ? people
      : people.filter((person) => {
          return person.name.toLowerCase().includes(query.toLowerCase())
        })

  return (
    <Combobox
      value={selectedPerson}
      virtual={{
        options: filteredPeople,

        disabled: (person) => !person.available,
      }}
      onChange={setSelectedPerson}
      onClose={() => setQuery('')}
    >
      <ComboboxInput
        aria-label="Assignee"
        displayValue={(person) => person?.name}
        onChange={(event) => setQuery(event.target.value)}
      />
      <ComboboxOptions anchor="bottom" className="w-(--input-width) border empty:invisible">
        {({ option: person }) => (

          <ComboboxOption value={person} className="data-disabled:opacity-50 data-focus:bg-blue-100">
            {person.name}
          </ComboboxOption>
        )}
      </ComboboxOptions>
    </Combobox>
  )
}
