Anatomy

To set up the accordion correctly, it's essential to understand its anatomy and the naming of its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Examples

Default Expanded State

Set the defaultValue prop to specify which item should be expanded by default.

import { Accordion } from '@ark-ui/react/accordion'
import { ChevronDownIcon } from 'lucide-react'

export const Basic = () => {
  return (
    <Accordion.Root defaultValue={['React']}>
      {['React', 'Solid', 'Vue'].map((item) => (
        <Accordion.Item key={item} value={item}>
          <Accordion.ItemTrigger>
            What is {item}?
            <Accordion.ItemIndicator>
              <ChevronDownIcon />
            </Accordion.ItemIndicator>
          </Accordion.ItemTrigger>
          <Accordion.ItemContent>
            {item} is a JavaScript library for building user interfaces.
          </Accordion.ItemContent>
        </Accordion.Item>
      ))}
    </Accordion.Root>
  )
}

import { Accordion } from '@ark-ui/solid/accordion'
import { ChevronDownIcon } from 'lucide-solid'
import { Index } from 'solid-js'

export const Basic = () => {
  return (
    <Accordion.Root defaultValue={['React']}>
      <Index each={['React', 'Solid', 'Vue']}>
        {(item) => (
          <Accordion.Item value={item()}>
            <Accordion.ItemTrigger>
              What is {item()}?
              <Accordion.ItemIndicator>
                <ChevronDownIcon />
              </Accordion.ItemIndicator>
            </Accordion.ItemTrigger>
            <Accordion.ItemContent>
              {item()} is a JavaScript library for building user interfaces.
            </Accordion.ItemContent>
          </Accordion.Item>
        )}
      </Index>
    </Accordion.Root>

    </Accordion.Item>
  </Accordion.Root>

Collapsible

Use the collapsible prop to allow the user to collapse all panels.

import { Accordion } from '@ark-ui/react/accordion'
import { ChevronDownIcon } from 'lucide-react'

export const Collapsible = () => {
  return (
    <Accordion.Root defaultValue={['React']} collapsible>

      </Accordion.ItemContent>
    </Accordion.Item>
  </Accordion.Root>
</template>

Multiple Panels

Use the multiple prop to allow multiple panels to be expanded simultaneously.

import { Accordion } from '@ark-ui/react/accordion'
import { ChevronDownIcon } from 'lucide-react'

export const Multiple = () => {
  return (
    <Accordion.Root defaultValue={['React']} multiple>
      {['React', 'Solid', 'Vue'].map((item) => (
        <Accordion.Item key={item} value={item}>

          </Accordion.ItemContent>
        </Accordion.Item>
      ))}
    </Accordion.Root>
  )
}

import { Accordion } from '@ark-ui/solid/accordion'
import { ChevronDownIcon } from 'lucide-solid'
import { Index } from 'solid-js'

export const Multiple = () => {
  return (
    <Accordion.Root value={['React']} multiple>

        {{ item }} is a JavaScript library for building user interfaces.
      </Accordion.ItemContent>
    </Accordion.Item>
  </Accordion.Root>
</template>

Horizontal Orientation

By default, the Accordion is oriented vertically. Use the orientation prop to switch to a horizontal layout.

import { Accordion } from '@ark-ui/react/accordion'
import { ChevronDownIcon } from 'lucide-react'

export const Horizontal = () => {
  return (
    <Accordion.Root defaultValue={['React']} orientation="horizontal">
      {['React', 'Solid', 'Vue'].map((item) => (
        <Accordion.Item key={item} value={item}>
          <Accordion.ItemTrigger>
            What is {item}?
            <Accordion.ItemIndicator>
              <ChevronDownIcon />
            </Accordion.ItemIndicator>
          </Accordion.ItemTrigger>
          <Accordion.ItemContent>
            {item} is a JavaScript library for building user interfaces.
          </Accordion.ItemContent>
        </Accordion.Item>
      ))}
    </Accordion.Root>
  )
}

import { Accordion } from '@ark-ui/solid/accordion'
import { ChevronDownIcon } from 'lucide-solid'
import { Index } from 'solid-js'

export const Horizontal = () => {
  return (
    <Accordion.Root defaultValue={['React']} orientation="horizontal">
      <Index each={['React', 'Solid', 'Vue']}>
        {(item) => (
          <Accordion.Item value={item()}>
            <Accordion.ItemTrigger>
              What is {item()}?
              <Accordion.ItemIndicator>
                <ChevronDownIcon />
              </Accordion.ItemIndicator>
            </Accordion.ItemTrigger>
            <Accordion.ItemContent>
              {item()} is a JavaScript library for building user interfaces.
            </Accordion.ItemContent>
          </Accordion.Item>
        )}
      </Index>
    </Accordion.Root>
  )
}

<script setup lang="ts">
import { Accordion } from '@ark-ui/vue/accordion'
import { ref } from 'vue'
import { ChevronDownIcon } from 'lucide-vue-next'

const items = ref(['React', 'Solid', 'Vue'])
</script>

<template>
  <Accordion.Root :defaultValue="['React']" orientation="horizontal">
    <Accordion.Item v-for="item in items" :key="item" :value="item">
      <Accordion.ItemTrigger>
        What is {{ item }}?
        <Accordion.ItemIndicator>
          <ChevronDownIcon />
        </Accordion.ItemIndicator>
      </Accordion.ItemTrigger>
      <Accordion.ItemContent>
        {{ item }} is a JavaScript library for building user interfaces.
      </Accordion.ItemContent>
    </Accordion.Item>
  </Accordion.Root>
</template>

Animate Content Size

Use the --height and/or --width CSS variables to animate the size of the content when it expands or closes:

@keyframes slideDown {
  from {
    opacity: 0.01;
    height: 0;
  }
  to {
    opacity: 1;
    height: var(--height);
  }
}

@keyframes slideUp {
  from {
    opacity: 1;
    height: var(--height);
  }
  to {
    opacity: 0.01;
    height: 0;
  }
}

[data-scope='accordion'][data-part='item-content'][data-state='open'] {
  animation: slideDown 250ms ease-in-out;
}

[data-scope='accordion'][data-part='item-content'][data-state='closed'] {
  animation: slideUp 200ms ease-in-out;
}

Using the Root Provider

The RootProvider component provides a context for the accordion. It accepts the value of the useAccordion hook. You can leverage it to access the component state and methods from outside the accordion.

import { Accordion, useAccordion } from '@ark-ui/react/accordion'
import { ChevronDownIcon } from 'lucide-react'

export const RootProvider = () => {
  const accordion = useAccordion({ defaultValue: ['React'] })

  return (
    <>
      <button onClick={() => accordion.setValue(['Vue'])}>Set to Vue</button>

      <Accordion.RootProvider value={accordion}>
        {['React', 'Solid', 'Vue'].map((item) => (
          <Accordion.Item key={item} value={item}>
            <Accordion.ItemTrigger>
              What is {item}?
              <Accordion.ItemIndicator>
                <ChevronDownIcon />
              </Accordion.ItemIndicator>
            </Accordion.ItemTrigger>
            <Accordion.ItemContent>
              {item} is a JavaScript library for building user interfaces.
            </Accordion.ItemContent>
          </Accordion.Item>
        ))}
      </Accordion.RootProvider>
    </>
  )
}

import { Accordion, useAccordion } from '@ark-ui/solid/accordion'
import { ChevronDownIcon } from 'lucide-solid'
import { Index } from 'solid-js'

export const RootProvider = () => {
  const accordion = useAccordion({ defaultValue: ['React'] })

  return (
    <>
      <button onClick={() => accordion().setValue(['Vue'])}>Set to Vue</button>

      <Accordion.RootProvider value={accordion}>
        <Index each={['React', 'Solid', 'Vue']}>
          {(item) => (
            <Accordion.Item value={item()}>
              <Accordion.ItemTrigger>
                What is {item()}?
                <Accordion.ItemIndicator>
                  <ChevronDownIcon />
                </Accordion.ItemIndicator>
              </Accordion.ItemTrigger>
              <Accordion.ItemContent>
                {item()} is a JavaScript library for building user interfaces.
              </Accordion.ItemContent>
            </Accordion.Item>
          )}
        </Index>
      </Accordion.RootProvider>
    </>
  )
}

<script setup lang="ts">
import { Accordion, useAccordion } from '@ark-ui/vue/accordion'
import { ref } from 'vue'
import { ChevronDownIcon } from 'lucide-vue-next'

const items = ref(['React', 'Solid', 'Vue'])

const accordion = useAccordion({ defaultValue: ['React'] })
</script>

<template>
  <button @click="accordion.setValue(['Vue'])">Set to Vue</button>

  <Accordion.RootProvider :value="accordion">
    <Accordion.Item v-for="item in items" :key="item" :value="item">
      <Accordion.ItemTrigger>
        What is {{ item }}?
        <Accordion.ItemIndicator>
          <ChevronDownIcon />
        </Accordion.ItemIndicator>
      </Accordion.ItemTrigger>
      <Accordion.ItemContent>
        {{ item }} is a JavaScript library for building user interfaces.
      </Accordion.ItemContent>
    </Accordion.Item>
  </Accordion.RootProvider>
</template>

If you're using the RootProvider component, you don't need to use the Root component.

Acessing the focused item

Use the focusedValue property to get the value of the focused accordion item.

import { Accordion } from '@ark-ui/react/accordion'
import { ChevronDownIcon } from 'lucide-react'

export const ContextFocusedValue = () => {
  return (
    <Accordion.Root defaultValue={['React']}>
      <Accordion.Context>
        {(context) => <span>Focused item: {context.focusedValue}</span>}
      </Accordion.Context>
      {['React', 'Solid', 'Vue'].map((item) => (
        <Accordion.Item key={item} value={item}>
          <Accordion.ItemTrigger>
            What is {item}?
            <Accordion.ItemIndicator>
              <ChevronDownIcon />
            </Accordion.ItemIndicator>
          </Accordion.ItemTrigger>
          <Accordion.ItemContent>
            {item} is a JavaScript library for building user interfaces.
          </Accordion.ItemContent>
        </Accordion.Item>
      ))}
    </Accordion.Root>
  )

      <Accordion.Context>
        {(context) => <span>Focused item: {context().focusedValue}</span>}
      </Accordion.Context>
      <Index each={['React', 'Solid', 'Vue']}>
        {(item) => (

Accessing an item's state

Use the getItemState method to get the state of an accordion item.

import { Accordion } from '@ark-ui/react/accordion'
import { ChevronDownIcon } from 'lucide-react'

export const ContextGetItemState = () => {
  const items = [{ value: 'React' }, { value: 'Solid', disabled: true }, { value: 'Vue' }]
