Tabs

Easily create accessible, fully customizable tab interfaces, with robust focus management and keyboard navigation support.

To get started, install Headless UI via npm:

npm install @headlessui/vue

Tabs are built using the TabGroup, TabList, Tab, TabPanels, and TabPanel components. By default the first tab is selected, and clicking on any tab or selecting it with the keyboard will activate the corresponding panel.

<template>
  <TabGroup>
    <TabList>
      <Tab>Tab 1</Tab>
      <Tab>Tab 2</Tab>
      <Tab>Tab 3</Tab>
    </TabList>
    <TabPanels>
      <TabPanel>Content 1</TabPanel>
      <TabPanel>Content 2</TabPanel>
      <TabPanel>Content 3</TabPanel>
    </TabPanels>
  </TabGroup>
</template>

<script setup>
  import { TabGroup, TabList, Tab, TabPanels, TabPanel } from '@headlessui/vue'
</script>

Headless UI keeps track of a lot of state about each component, like which tab option is currently checked, whether a popover is open or closed, or which item in a menu is currently active 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.

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

For example, the Tab component exposes a selected state, which tells you if the tab is currently selected.

<template>
  <TabGroup>
    <TabList>
      <!-- Use the `selected` state to conditionally style the selected tab. -->
      <Tab as="template" v-slot="{ selected }">
        <button
          :class="{ 'bg-blue-500 text-white': selected, 'bg-white text-black': !selected }"
        >
          Tab 1
        </button>
      </Tab>
      <!-- ... -->
    </TabList>
    <TabPanels>
      <TabPanel>Content 1</TabPanel>
      <!-- ... -->
    </TabPanels>
  </TabGroup>
</template>

<script setup>
  import { TabGroup, TabList, Tab, TabPanels, TabPanel } from '@headlessui/vue'
</script>

For the complete slot props API for each component, see the component API documentation.

Each component also exposes information about its current state via a data-headlessui-state attribute that you can use to conditionally apply different styles.

When any of the states in the slot props API are true, they will be listed in this attribute as space-separated strings so you can target them with a CSS attribute selector in the form [attr~=value].

For example, here's what the TabGroup component with some child Tab components renders when the second tab is selected:

<!-- Rendered `TabGroup` -->
<div>
  <button data-headlessui-state="">Tab 1</button>
  <button data-headlessui-state="selected">Tab 2</button>
  <button data-headlessui-state="">Tab 3</button>
</div>
<div>
  <div data-headlessui-state="">Content 1</div>
  <div data-headlessui-state="selected">Content 2</div>
  <div data-headlessui-state="">Content 3</div>
</div>

If you are using Tailwind CSS, you can use the @headlessui/tailwindcss plugin to target this attribute with modifiers like ui-open:*:

<template>
  <TabGroup>
    <TabList>
      <Tab
        class="ui-selected:bg-blue-500 ui-selected:text-white ui-not-selected:bg-white ui-not-selected:text-black"
      >
        Tab 1
      </Tab>
      <!-- ... -->
    </TabList>
    <TabPanels>
      <TabPanel>Content 1</TabPanel>
      <!-- ... -->
    </TabPanels>
  </TabGroup>
</template>

<script setup>
  import { TabGroup, TabList, Tab, TabPanels, TabPanel } from '@headlessui/vue'
</script>

To disable a tab, use the disabled prop on the Tab component. Disabled tabs cannot be selected with the mouse, and are also skipped when navigating the tab list using the keyboard.

<template>
  <TabGroup>
    <TabList>
      <Tab>Tab 1</Tab>
      <Tab disabled>Tab 2</Tab>
      <Tab>Tab 3</Tab>
    </TabList>
    <TabPanels>
      <TabPanel>Content 1</TabPanel>
      <TabPanel>Content 2</TabPanel>
      <TabPanel>Content 3</TabPanel>
    </TabPanels>
  </TabGroup>
</template>

<script setup>
  import { TabGroup, TabList, Tab, TabPanels, TabPanel } from '@headlessui/vue'
</script>

By default, tabs are automatically selected as the user navigates through them using the arrow keys.

If you'd rather not change the current tab until the user presses Enter or Space, use the manual prop on the TabGroup component. This can be helpful if selecting a tab performs an expensive operation and you don't want to run it unnecessarily.

<template>
  <TabGroup manual>
    <TabList>
      <Tab>Tab 1</Tab>
      <Tab>Tab 2</Tab>
      <Tab>Tab 3</Tab>
    </TabList>
    <TabPanels>
      <TabPanel>Content 1</TabPanel>
      <TabPanel>Content 2</TabPanel>
      <TabPanel>Content 3</TabPanel>
    </TabPanels>
  </TabGroup>
</template>

<script setup>
  import { TabGroup, TabList, Tab, TabPanels, TabPanel } from '@headlessui/vue'
</script>

The manual prop has no impact on mouse interactions — tabs will still be selected as soon as they are clicked.

If you've styled your TabList to appear vertically, use the vertical prop to enable navigating with the up and down arrow keys instead of left and right, and to update the aria-orientation attribute for assistive technologies.

<template>
  <TabGroup vertical>
    <TabList>
      <Tab>Tab 1</Tab>
      <Tab>Tab 2</Tab>
      <Tab>Tab 3</Tab>
    </TabList>
    <TabPanels>
      <TabPanel>Content 1</TabPanel>
      <TabPanel>Content 2</TabPanel>
      <TabPanel>Content 3</TabPanel>
    </TabPanels>
  </TabGroup>
</template>

<script setup>
  import { TabGroup, TabList, Tab, TabPanels, TabPanel } from '@headlessui/vue'
</script>

To change which tab is selected by default, use the :defaultIndex="number" prop on the TabGroup component.

<template>
  <TabGroup :defaultIndex="1">
    <TabList>
      <Tab>Tab 1</Tab>

      <!-- Selects this tab by default -->
      <Tab>Tab 2</Tab>
      <Tab>Tab 3</Tab>
    </TabList>
    <TabPanels>
      <TabPanel>Content 1</TabPanel>

      <!-- Displays this tab by default -->
      <TabPanel>Content 2</TabPanel>
      <TabPanel>Content 3</TabPanel>
    </TabPanels>
  </TabGroup>
</template>

<script setup>
  import { TabGroup, TabList, Tab, TabPanels, TabPanel } from '@headlessui/vue'
</script>

If you happen to provide an index that is out of bounds, then the last non-disabled tab will be selected on initial render. (For example, <TabGroup :defaultIndex="5" in the example above would render the third panel as selected.)

To run a function whenever the selected tab changes, use the @change event on the TabGroup component.

<template>
  <TabGroup @change="changeTab">
    <TabList>
      <Tab>Tab 1</Tab>
      <Tab>Tab 2</Tab>
      <Tab>Tab 3</Tab>
    </TabList>
    <TabPanels>
      <TabPanel>Content 1</TabPanel>
      <TabPanel>Content 2</TabPanel>
      <TabPanel>Content 3</TabPanel>
    </TabPanels>
  </TabGroup>
</template>

<script setup>
  import { TabGroup, TabList, Tab, TabPanels, TabPanel } from '@headlessui/vue'

  function changeTab(index) {
    console.log('Changed active tab to:', index)
  }</script>

The tabs component can also be used as a controlled component. To do this, provide the selectedIndex and manage the state yourself.

<template>
  <TabGroup :selectedIndex="selectedTab" @change="changeTab">
    <TabList>
      <Tab>Tab 1</Tab>
      <Tab>Tab 2</Tab>
      <Tab>Tab 3</Tab>
    </TabList>
    <TabPanels>
      <TabPanel>Content 1</TabPanel>
      <TabPanel>Content 2</TabPanel>
      <TabPanel>Content 3</TabPanel>
    </TabPanels>
  </TabGroup>
</template>

<script setup>
  import { ref } from 'vue'
  import { TabGroup, TabList, Tab, TabPanels, TabPanel } from '@headlessui/vue'

  const selectedTab = ref(0)
  function changeTab(index) {
    selectedTab.value = index
  }</script>

Clicking a Tab will select that tab and display the corresponding TabPanel.

All interactions apply when a Tab component is focused.

Command	Description
`ArrowLeft` and `ArrowRight`	Selects the previous/next non-disabled tab.
`ArrowUp` and `ArrowDown`when `vertical` is set	Selects the previous/next non-disabled tab.
`Home` or `PageUp`	Selects the first non-disabled tab.
`End` or `PageDown`	Selects the last non-disabled tab.
`Enter` or `Space` when `manual` is set	Activates the selected tab.

All relevant ARIA attributes are automatically managed.

The main TabGroup component.

Prop	Default	Description
`as`	`template`	`String \| Component` The element or component the `TabGroup` should render as.
`defaultIndex`	`0`	`Number` The default selected index
`selectedIndex`	—	`number` The selected index if you want to use the Tabs component as a controlled component.
`vertical`	`false`	`Boolean` When true, the orientation of the `TabList` will be `vertical`, otherwise it will be `horizontal`.
