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>

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

To style the selected Tab, use the selected slot prop, which tells you whether or not that tab is currently selected.

<template>
  <TabGroup>
    <TabList>
      <Tab v-slot="{ selected }" as="template">
        <button
          :class="[selected ? 'bg-blue-500 text-white' : 'bg-white text-black']"
        >
          Tab 1
        </button>
      </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 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 { 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.
