Combobox (Autocomplete)

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, Combobox.Input, Combobox.Button, Combobox.Options, Combobox.Option and Combobox.Label components.

The Combobox.Input will automatically open/close the Combobox.Options when searching.

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 { useState } from 'react'
import { Combobox } from '@headlessui/react'

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

function MyCombobox() {
  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}>
      <Combobox.Input onChange={(event) => setQuery(event.target.value)} />
      <Combobox.Options>
        {filteredPeople.map((person) => (
          <Combobox.Option key={person} value={person}>
            {person}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

In the previous example we used a list of string values as data, but you can also use objects with additional information. The only caveat is that you have to provide a displayValue to the input. This is important so that a string based version of your object can be rendered in the Combobox.Input.

import { useState } from 'react'
import { Combobox } from '@headlessui/react'

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

function MyCombobox() {
  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}>
      <Combobox.Input
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person.name}
      />
      <Combobox.Options>
        {filteredPeople.map((person) => (
          <Combobox.Option
            key={person.id}
            value={person}
            disabled={person.unavailable}
          >
            {person.name}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

This is a headless component so there are no styles included by default. Instead, the components expose useful information via render props that you can use to apply the styles you'd like to apply yourself.

To style the active Combobox.Option you can read the active render prop argument, which tells you whether or not that combobox option is the option that is currently focused via the mouse or keyboard.

To style the selected Combobox.Option you can read the selected render prop argument, which tells you whether or not that combobox option is the option that is currently the value passed to the Combobox.

Note that an option can be both active and selected at the same time.

import { useState, Fragment } from 'react'
import { Combobox } from '@headlessui/react'
import { CheckIcon } from '@heroicons/react/solid'

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 MyCombobox() {
  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}>
      <Combobox.Input
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person.name}
      />
      <Combobox.Options>
        {filteredPeople.map((person) => (
          /* Use the `active` state to conditionally style the active option. */
          /* Use the `selected` state to conditionally style the selected option. */
          <Combobox.Option key={person.id} value={person} as={Fragment}>
            {({ active, selected }) => (
              <li
                className={`${
                  active ? 'bg-blue-500 text-white' : 'bg-white text-black'
                }`}
              >
                {selected && <CheckIcon />}
                {person.name}
              </li>
            )}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </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 { useState } from 'react'
import { Combobox } from '@headlessui/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 MyCombobox() {
  const [selectedPeople, setSelectedPeople] = useState([people[0], people[1]])
  return (
    <Combobox value={selectedPeople} onChange={setSelectedPeople} multiple>
      {selectedPeople.length > 0 && (
        <ul>
          {selectedPeople.map((person) => (
            <li key={person.id}>{person.name}</li>
          ))}
        </ul>
      )}
      <Combobox.Input />
      <Combobox.Options>
        {people.map((person) => (
          <Combobox.Option key={person.id} value={person}>
            {person.name}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

The displayValue prop is omitted because the selectedPeople is already displayed in a list above the input. If you wish to display the items in the Combobox.Input then the displayValue receives an array.

import { useState } from 'react'
import { Combobox } from '@headlessui/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 MyCombobox() {
  const [selectedPeople, setSelectedPeople] = useState([people[0], people[1]])
  return (
    <Combobox value={selectedPeople} onChange={setSelectedPeople} multiple>
      <Combobox.Input
        displayValue={(people) =>
          people.map((person) => person.name).join(', ')
        }
      />
      <Combobox.Options>
        {people.map((person) => (
          <Combobox.Option key={person.id} value={person}>
            {person.name}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

This will keep the combobox open when you are selecting options, and choosing an option will toggle it in place.

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

By default the Combobox will use the input contents as the label for screenreaders. If you'd like more control over what is announced to assistive technologies, use the Combobox.Label component.

import { useState } from 'react'
import { Combobox } from '@headlessui/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 MyCombobox() {
  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}>
      <Combobox.Label>Assignee:</Combobox.Label>
      <Combobox.Input
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person.name}
      />
      <Combobox.Options>
        {filteredPeople.map((person) => (
          <Combobox.Option key={person.id} value={person}>
            {person.name}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

If you add the name prop to your combobox, hidden input elements will be rendered and kept in sync with your selected value.

import { useState } from 'react'
import { Combobox } from '@headlessui/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
        value={selectedPerson}
        onChange={setSelectedPerson}
        name="assignee"
      >
        <Combobox.Input
          onChange={(event) => setQuery(event.target.value)}
          displayValue={(person) => person.name}
        />
        <Combobox.Options>
          {filteredPeople.map((person) => (
            <Combobox.Option key={person.id} value={person}>
              {person.name}
            </Combobox.Option>
          ))}
        </Combobox.Options>
      </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:

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

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

import { useState } from 'react'
import { Combobox } from '@headlessui/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}>
      <Combobox.Input
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person.name}
      />
      <Combobox.Options>
        {query.length > 0 && (
          <Combobox.Option value={{ id: null, name: query }}>
            Create "{query}"
          </Combobox.Option>
        )}
        {filteredPeople.map((person) => (
          <Combobox.Option key={person.id} value={person}>
            {person.name}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

Depending on what you're building it can sometimes make sense to render additional information about the active option outside of the <Combobox.Options>. 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 { useState } from 'react'
import { Combobox } from '@headlessui/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 MyCombobox() {
  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}>
      {({ activeOption }) => (
        <>
          <Combobox.Input
            onChange={(event) => setQuery(event.target.value)}
            displayValue={(person) => person.name}
          />
          <Combobox.Options>
            {filteredPeople.map((person) => (
              <Combobox.Option key={person.id} value={person}>
                {person.name}
              </Combobox.Option>
            ))}
          </Combobox.Options>

          {activeOption && (
            <div>The current active user is: {activeOption.name}</div>
          )}
        </>
      )}
    </Combobox>
  )
}

The activeOption will be the value of the current active Combobox.Option.

By default, your Combobox.Options instance will be shown/hidden automatically based on the internal open state tracked within the Combobox component itself.

import { useState } from 'react'
import { Combobox } from '@headlessui/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 MyCombobox() {
  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}>
      <Combobox.Input
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person.name}
      />

      {/*
        By default, this will automatically show/hide when typing in the
        Combobox.Input, or when pressing the Combobox.Button.
      */}
      <Combobox.Options>
        {filteredPeople.map((person) => (
          <Combobox.Option key={person.id} value={person}>
            {person.name}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

If you'd rather handle this yourself (perhaps because you need to add an extra wrapper element for one reason or another), you can add a static prop to the Combobox.Options instance to tell it to always render, and inspect the open render prop provided by Combobox to control which element is shown/hidden yourself.

import { useState } from 'react'
import { Combobox } from '@headlessui/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 MyCombobox() {
  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 }) => (
        <>
          <Combobox.Input
            onChange={(event) => setQuery(event.target.value)}
            displayValue={(person) => person.name}
          />
          {open && (
            <div>
              {/*
                Using `static`, `Combobox.Options` is always rendered and
                ignores the `open` state.
              */}
              <Combobox.Options static>
                {filteredPeople.map((person) => (
                  <Combobox.Option key={person.id} value={person}>
                    {person.name}
                  </Combobox.Option>
                ))}
              </Combobox.Options>
            </div>
          )}
        </>
      )}
    </Combobox>
  )
}

Use the disabled prop to disable a Combobox.Option. This will make it unselectable via mouse and keyboard, and it will be skipped when pressing the up/down arrows.

import { useState } from 'react'
import { Combobox } from '@headlessui/react'

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

function MyCombobox() {
  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}>
      <Combobox.Input
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person.name}
      />
      <Combobox.Options>
        {filteredPeople.map((person) => (
          /* Disabled options will be skipped by keyboard navigation. */
          <Combobox.Option
            key={person.id}
            value={person}
            disabled={person.unavailable}
          >
            <span className={person.unavailable ? 'opacity-75' : ''}>
              {person.name}
            </span>
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

By default, once you've selected a value in a combobox there is no way to clear the combobox back to an empty value — when you clear the input and tab away, the value returns to the previously selected value.

If you want to support empty values in your combobox, use the nullable prop.

import { useState } from 'react'
import { Combobox } from '@headlessui/react'

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

function MyCombobox() {
  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} nullable>
      <Combobox.Input
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person?.name}
      />
      <Combobox.Options>
        {filteredPeople.map((person) => (
          <Combobox.Option key={person.id} value={person}>
            {person.name}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

When the nullable prop is used, clearing the input and navigating away from the element will invoke your onChange and displayValue callbacks with null.

This prop doesn't do anything when allowing multiple values because options are toggled on and off, resulting in an empty array (rather than null) if nothing is selected.

To animate the opening/closing of the combobox panel, use the provided Transition component. All you need to do is wrap the Combobox.Options in a <Transition>, and the transition will be applied automatically.

import { useState } from 'react'
import { Combobox, Transition } from '@headlessui/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 MyCombobox() {
  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}>
      <Combobox.Input
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person.name}
      />
      <Transition
        enter="transition duration-100 ease-out"
        enterFrom="transform scale-95 opacity-0"
        enterTo="transform scale-100 opacity-100"
        leave="transition duration-75 ease-out"
        leaveFrom="transform scale-100 opacity-100"
        leaveTo="transform scale-95 opacity-0"
      >
        <Combobox.Options>
          {filteredPeople.map((person) => (
            <Combobox.Option key={person.id} value={person}>
              {person.name}
            </Combobox.Option>
          ))}
        </Combobox.Options>
      </Transition>
    </Combobox>
  )
}

By default our built-in Transition component automatically communicates with the Combobox components to handle the open/closed states. However, if you require more control over this behavior, you can explicitly control it:

import { useState } from 'react'
import { Combobox, Transition } from '@headlessui/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 MyCombobox() {
  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 }) => (
        <>
          <Combobox.Input
            onChange={(event) => setQuery(event.target.value)}
            displayValue={(person) => person.name}
          />
          {/*
            Use the Transition + open render prop argument to add transitions.
          */}
          <Transition
            show={open}
            enter="transition duration-100 ease-out"
            enterFrom="transform scale-95 opacity-0"
            enterTo="transform scale-100 opacity-100"
            leave="transition duration-75 ease-out"
            leaveFrom="transform scale-100 opacity-100"
            leaveTo="transform scale-95 opacity-0"
          >
            {/*
              Don't forget to add `static` to your Combobox.Options!
            */}
            <Combobox.Options static>
              {filteredPeople.map((person) => (
                <Combobox.Option key={person.id} value={person}>
                  {person.name}
                </Combobox.Option>
              ))}
            </Combobox.Options>
          </Transition>
        </>
      )}
    </Combobox>
  )
}

Because they're renderless, Headless UI components also compose well with other animation libraries in the React ecosystem like Framer Motion and React Spring.

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

For example, Combobox.Label renders a label by default, Combobox.Input renders an input, Combobox.Button renders a button, Combobox.Options renders a ul, and Combobox.Option renders a li. By contrast, Combobox does not render an element, and instead renders its children directly.

This is easy to change using the as prop, which exists on every component.

import { useState } from 'react'
import { Combobox } from '@headlessui/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 MyCombobox() {
  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 (
    /* Render a `div` instead of a React.Fragment */
    <Combobox as="div" value={selectedPerson} onChange={setSelectedPerson}>
      <Combobox.Input
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person.name}
      />

      {/* Render a `div` instead of a `ul` */}
      <Combobox.Options as="div">
        {filteredPeople.map((person) => (
          /* Render a `span` instead of a `li` */
          <Combobox.Option as="span" key={person.id} value={person}>
            {person.name}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

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

import { useState, Fragment } from 'react'
import { Combobox } from '@headlessui/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 MyCombobox() {
  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}>
      {/* Render a `Fragment` instead of an `input` */}
      <Combobox.Input
        as={Fragment}
        onChange={(event) => setQuery(event.target.value)}
        displayValue={(person) => person.name}
      >
        <input />
      </Combobox.Input>
      <Combobox.Options>
        {filteredPeople.map((person) => (
          <Combobox.Option key={person.id} value={person}>
            {person.name}
          </Combobox.Option>
        ))}
      </Combobox.Options>
    </Combobox>
  )
}

When a Combobox is toggled open, the Combobox.Input stays focused.

The Combobox.Button is ignored for the default tab flow, this means that pressing Tab in the Combobox.Input will skip passed the Combobox.Button.

Clicking a Combobox.Button toggles the options list open and closed. Clicking anywhere outside of the options list will close the combobox.
