API#

useDisclosure(
  props: AriaDisclosureProps,
  state: DisclosureState,
  ref: RefObject<HTMLElement
    |  | null>
): DisclosureAria

Features#

A disclosure is a collapsible section of content. It is composed of a trigger button and a panel that contains the content. useDisclosure can be used to implement these in an accessible way.

Support for mouse, touch, and keyboard interactions to open and close the disclosure
Support for disabled disclosures
Follows the disclosure ARIA pattern, semantically linking the trigger button and panel
Uses hidden="until-found" in supported browsers, enabling find-in-page search support and improved search engine visibility for collapsed content

Anatomy#

A disclosure consists of a trigger button and a panel. Clicking on or pressing Enter or Space while the trigger button is focused toggles the visibility of the panel.

useDisclosure returns props to spread onto the trigger button and panel.

Name	Type	Description
`buttonProps`	`AriaButtonProps`	Props for the disclosure button.
`panelProps`	`HTMLAttributes<HTMLElement>`	Props for the disclosure panel.

State is managed by the useDisclosureState hook in @react-stately/disclosure. The state object should be passed as an option to useDisclosure.

Example#

This example displays a basic disclosure with a button that toggles the visibility of the panel.

import {useButton, useDisclosure} from 'react-aria';
import {useDisclosureState} from 'react-stately';
import {mergeProps, useFocusRing} from 'react-aria';

function Disclosure(props) {
  let state = useDisclosureState(props);
  let panelRef = React.useRef<HTMLDivElement | null>(null);
  let triggerRef = React.useRef<HTMLButtonElement | null>(null);
  let { buttonProps: triggerProps, panelProps } = useDisclosure(
    props,
    state,
    panelRef
  );
  let { buttonProps } = useButton(triggerProps, triggerRef);
  let { isFocusVisible, focusProps } = useFocusRing();

  return (
    <div className="disclosure">
      <h3>
        <button
          className="trigger"
          ref={triggerRef}
          {...mergeProps(buttonProps, focusProps)}
          style={{ outline: isFocusVisible ? '2px solid dodgerblue' : 'none' }}
        >
          <svg viewBox="0 0 24 24">
            <path d="m8.25 4.5 7.5 7.5-7.5 7.5" />

Usage#

The following examples show how to use the Disclosure component created in the above example.

Default expansion#

Whether or not the disclosure is expanded or not by default can be set with the defaultExpanded prop.

<Disclosure title="System Requirements" defaultExpanded>
  Details about system requirements here.
</Disclosure>

<Disclosure title="System Requirements" defaultExpanded>
  Details about system requirements here.
</Disclosure>

<Disclosure
  title="System Requirements"
  defaultExpanded
>
  Details about system
  requirements here.
</Disclosure>

Controlled expansion#

Expansion can be controlled using the isExpanded prop, paired with the onExpandedChange event. The onExpandedChange event is fired when the user presses the trigger button.

function ControlledDisclosure(props) {
  let [isExpanded, setExpanded] = React.useState(false);

  return (
    <Disclosure
      title="System Requirements"
      isExpanded={isExpanded}
      onExpandedChange={setExpanded}
    >
      Details about system requirements here.
    </Disclosure>
  );
}

function ControlledDisclosure(props) {
  let [isExpanded, setExpanded] = React.useState(false);

  return (
    <Disclosure
      title="System Requirements"
      isExpanded={isExpanded}
      onExpandedChange={setExpanded}
    >
      Details about system requirements here.
    </Disclosure>
  );
}

function ControlledDisclosure(
  props
) {
  let [
    isExpanded,
    setExpanded
  ] = React.useState(
    false
  );

  return (
    <Disclosure
      title="System Requirements"
      isExpanded={isExpanded}
      onExpandedChange={setExpanded}
    >
      Details about
      system requirements
      here.
    </Disclosure>
  );
}

Disabled#

A disclosure can be disabled with the isDisabled prop. This will disable the trigger button and prevent the panel from being opened or closed.

<Disclosure title="System Requirements" isDisabled>
  Details about system requirements here.
</Disclosure>

<Disclosure title="System Requirements" isDisabled>
  Details about system requirements here.
</Disclosure>

<Disclosure
  title="System Requirements"
  isDisabled
>
  Details about system
  requirements here.
</Disclosure>

Disclosure Group#

A disclosure group (i.e. accordion) is a set of disclosures where only one disclosure can be expanded at a time. The following example shows how to create a DisclosureGroup component with the useDisclosureGroupState hook. We'll also create a DisclosureItem component that uses the DisclosureGroupState context for managing its state.

import {useId} from 'react-aria';
import {useDisclosureGroupState} from 'react-stately';

const DisclosureGroupStateContext = React.createContext(null);

function DisclosureGroup(props) {
  let state = useDisclosureGroupState(props);

  return (
    <div className="group">
      <DisclosureGroupStateContext.Provider value={state}>
        {props.children}
      </DisclosureGroupStateContext.Provider>
    </div>
  );
}

function DisclosureItem(props) {
  let defaultId = useId();
  let id = props.id || defaultId;
  let groupState = React.useContext(DisclosureGroupStateContext);
  let isExpanded = groupState
    ? groupState.expandedKeys.has(id)
    : props.isExpanded;
  let state = useDisclosureState({
    ...props,
    isExpanded,
    onExpandedChange(isExpanded) {
      if (groupState) {
        groupState.toggleKey(id);
      }

      props.onExpandedChange?.(isExpanded);
    }
  });

  let panelRef = React.useRef<HTMLDivElement | null>(null);
  let triggerRef = React.useRef<HTMLButtonElement | null>(null);
  let isDisabled = props.isDisabled || groupState?.isDisabled || false;
  let { buttonProps: triggerProps, panelProps } = useDisclosure(
    {
      ...props,
      isExpanded,
      isDisabled
    },
    state,
    panelRef
  );
  let { buttonProps } = useButton(triggerProps, triggerRef);
  let { isFocusVisible, focusProps } = useFocusRing();

  return (
    <div className="disclosure">
      <h3>
        <button
          className="trigger"
          ref={triggerRef}
          {...mergeProps(buttonProps, focusProps)}

Usage#

The following examples show how to use the DisclosureGroup component created in the above example.

<DisclosureGroup>
  <DisclosureItem title="Personal Information">
    Personal information form here.
  </DisclosureItem>
  <DisclosureItem title="Billing Address">
    Billing address form here.
  </DisclosureItem>
</DisclosureGroup>

<DisclosureGroup>
  <DisclosureItem title="Personal Information">
    Personal information form here.
  </DisclosureItem>
  <DisclosureItem title="Billing Address">
    Billing address form here.
  </DisclosureItem>
</DisclosureGroup>

<DisclosureGroup>
  <DisclosureItem title="Personal Information">
    Personal
    information form
    here.
  </DisclosureItem>
  <DisclosureItem title="Billing Address">
    Billing address
    form here.
  </DisclosureItem>
</DisclosureGroup>

Default expansion#

Which disclosure is expanded by default can be set with the defaultExpandedKeys prop.

<DisclosureGroup defaultExpandedKeys={['billing']}>
  <DisclosureItem id="personal" title="Personal Information">
    Personal information form here.
  </DisclosureItem>
  <DisclosureItem id="billing" title="Billing Address">
    Billing address form here.
  </DisclosureItem>
</DisclosureGroup>

<DisclosureGroup defaultExpandedKeys={['billing']}>
  <DisclosureItem
    id="personal"
    title="Personal Information"
  >
    Personal information form here.
  </DisclosureItem>
  <DisclosureItem id="billing" title="Billing Address">
    Billing address form here.
  </DisclosureItem>
</DisclosureGroup>

<DisclosureGroup
  defaultExpandedKeys={[
    'billing'
  ]}
>
  <DisclosureItem
    id="personal"
    title="Personal Information"
  >
    Personal
    information form
    here.
  </DisclosureItem>
  <DisclosureItem
    id="billing"
    title="Billing Address"
  >
    Billing address
    form here.
  </DisclosureItem>
</DisclosureGroup>

Controlled expansion#

Expansion can be controlled using the expandedKeys prop, paired with the onExpandedChange event. The onExpandedChange event is fired when one of the disclosures is expanded or collapsed.

function ControlledDisclosureGroup(props) {
  let [expandedKeys, setExpandedKeys] = React.useState(['personal']);

  return (
    <DisclosureGroup
      expandedKeys={expandedKeys}
      onExpandedChange={setExpandedKeys}
    >
      <DisclosureItem id="personal" title="Personal Information">
        Personal information form here.
      </DisclosureItem>
      <DisclosureItem id="billing" title="Billing Address">
        Billing address form here.
      </DisclosureItem>
    </DisclosureGroup>
  );
}

function ControlledDisclosureGroup(props) {
  let [expandedKeys, setExpandedKeys] = React.useState([
    'personal'
  ]);

  return (
    <DisclosureGroup
      expandedKeys={expandedKeys}
      onExpandedChange={setExpandedKeys}
    >
      <DisclosureItem
        id="personal"

Multiple expanded#

Multiple disclosures can be expanded at the same time by setting the allowsMultipleExpanded prop to true.

<DisclosureGroup allowsMultipleExpanded>
  <DisclosureItem title="Personal Information">
    Personal information form here.
  </DisclosureItem>
  <DisclosureItem title="Billing Address">
    Billing address form here.
  </DisclosureItem>
</DisclosureGroup>

<DisclosureGroup allowsMultipleExpanded>
  <DisclosureItem title="Personal Information">
    Personal information form here.
  </DisclosureItem>
  <DisclosureItem title="Billing Address">
    Billing address form here.
  </DisclosureItem>
</DisclosureGroup>

Disabled#

An entire disclosure group can be disabled with the isDisabled prop. This will disable all trigger buttons and prevent the panels from being opened or closed.

<DisclosureGroup isDisabled>
  <DisclosureItem title="Personal Information">
    Personal information form here.
  </DisclosureItem>
  <DisclosureItem title="Billing Address">
    Billing address form here.
  </DisclosureItem>
</DisclosureGroup>

<DisclosureGroup isDisabled>
  <DisclosureItem title="Personal Information">
    Personal information form here.
  </DisclosureItem>
  <DisclosureItem title="Billing Address">
    Billing address form here.
  </DisclosureItem>
</DisclosureGroup>

<DisclosureGroup

Name	Type	Default	Description
`isDisabled`	`boolean`	—	Whether the button is disabled.
`children`	`ReactNode`	—	The content to display in the button.
`onPress`	`( (e: PressEvent )) => void`	—	Handler that is called when the press is released over the target.

`onPressUp`	`( (e: PressEvent )) => void`	—	Handler that is called when a press is released over the target, regardless of whether it started on the target or not.
`onClick`	`( (e: MouseEvent<FocusableElement> )) => void`	—	Not recommended – use `onPress` instead. `onClick` is an alias for `onPress` provided for compatibility with other libraries. `onPress` provides additional event details for non-mouse interactions.
`autoFocus`	`boolean`	—	Whether the element should receive focus on render.
`onFocus`	`( (e: FocusEvent<Target> )) => void`	—	Handler that is called when the element receives focus.

`value`	`string`	—	The value associated with the button's name when it's submitted with the form data.
`excludeFromTabOrder`	`boolean`	—	Whether to exclude the element from the sequential tab order. If true, the element will not be focusable via the keyboard by tabbing.
