Features#

Disclosures can be built with the <details> and <summary> HTML element, but this can be difficult to style especially when adding adjacent interactive elements, like buttons, to the disclosure's heading. Disclosure helps achieve accessible disclosures implemented with the correct ARIA pattern while making custom styling easy.

Flexible - Structured such that it can be used standalone or combined with other disclosures to form a DisclosureGroup
Keyboard Interaction - When focused, a disclosure's visibility can be toggled with either the Enter or Space key, and the appropriate ARIA attributes are automatically applied.
Accessible - Uses hidden="until-found" in supported browsers, enabling find-in-page search support and improved search engine visibility for collapsed content
Styleable - Keyboard focus, disabled and expanded states are provided for easy styling. These states only apply when interacting with an appropriate input device, unlike CSS pseudo classes.

Anatomy#

A disclosure consists of a button and panel of content. The button contains the label representing content within the panel, and the panel is the section of content that is associated with the button which is either expanded or collapsed.

import {Button, Disclosure, DisclosurePanel, Heading} from 'react-aria-components';

<Disclosure>
  <Heading>
    <Button />
  </Heading>
  <DisclosurePanel />
</Disclosure>

import {
  Button,
  Disclosure,
  DisclosurePanel,
  Heading
} from 'react-aria-components';

<Disclosure>
  <Heading>
    <Button />
  </Heading>
  <DisclosurePanel />
</Disclosure>

import {
  Button,
  Disclosure,
  DisclosurePanel,
  Heading
} from 'react-aria-components';

<Disclosure>
  <Heading>
    <Button />
  </Heading>
  <DisclosurePanel />
</Disclosure>

Reusable wrappers#

If you will use a Disclosure in multiple places in your app, you can wrap all of the pieces into a reusable component. This way, the DOM structure, styling code, and other logic are defined in a single place and reused everywhere to ensure consistency.

This example wraps Disclosure and all of its children together into a single component.

import type {DisclosureProps} from 'react-aria-components';

interface MyDisclosureProps extends Omit<DisclosureProps, 'children'> {
  title?: string,
  children?: React.ReactNode
}

function MyDisclosure({title, children, ...props}: MyDisclosureProps) {
  return (
    <Disclosure {...props}>
      <Heading>
        <Button slot="trigger">
          <svg viewBox="0 0 24 24">
            <path d="m8.25 4.5 7.5 7.5-7.5 7.5" />
          </svg>
          {title}
        </Button>
      </Heading>
      <DisclosurePanel>
        <p>{children}</p>
      </DisclosurePanel>
    </Disclosure>
  )
}

An uncontrolled Disclosure can be expanded by default using the defaultExpanded prop.

<MyDisclosure title="Download, Install, and Set Up" defaultExpanded >
  Instructions on how to download, install, and set up
</MyDisclosure>

<MyDisclosure
  title="Download, Install, and Set Up"
  defaultExpanded

A controlled Disclosure can be expanded and collapsed using isExpanded and onExpandedChange

function ControlledExpanded() {
  let [isExpanded, setIsExpanded] = React.useState(true);

  return (
    <MyDisclosure
      title="Download, Install, and Set Up"
      isExpanded={isExpanded}
      onExpandedChange={setIsExpanded}
    >
      Instructions on how to download, install, and set up
    </MyDisclosure>
  );
}

<ControlledExpanded />

function ControlledExpanded() {
  let [isExpanded, setIsExpanded] = React.useState(true);

  return (
    <MyDisclosure
      title="Download, Install, and Set Up"
      isExpanded={isExpanded}
      onExpandedChange={setIsExpanded}
    >
      Instructions on how to download, install, and set up
    </MyDisclosure>
  );
}

<ControlledExpanded />

function ControlledExpanded() {
  let [
    isExpanded,
    setIsExpanded
  ] = React.useState(
    true
  );

  return (
    <MyDisclosure

      isExpanded={isExpanded}
      onExpandedChange={setIsExpanded}
    >
      Instructions on how
      to download,
      install, and set up
    </MyDisclosure>
  );
}

<ControlledExpanded />

Disabled#

A Disclosure can be disabled using the isDisabled prop.

<MyDisclosure title="Introduction to Knitting" isDisabled >

Styling#

React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin className attribute which can be targeted using CSS selectors. These follow the react-aria-ComponentName naming convention.

.react-aria-Disclosure {
  /* ... */
}

.react-aria-Disclosure {
  /* ... */
}

.react-aria-Disclosure {
  /* ... */
}

A custom className can also be specified on any component. This overrides the default className provided by React Aria with your own.

<Disclosure className="my-disclosure">
  {/* ... */}
</Disclosure>

<Disclosure className="my-disclosure">
  {/* ... */}
</Disclosure>

<Disclosure className="my-disclosure">
  {/* ... */}
</Disclosure>

In addition, some components support multiple UI states (e.g. focused, placeholder, readonly, etc.). React Aria components expose states using data attributes, which you can target in CSS selectors. For example:

.react-aria-Disclosure[data-expanded] {
  /* ... */
}

.react-aria-Disclosure[data-expanded] {
  /* ... */
}

.react-aria-Disclosure[data-expanded] {
  /* ... */
}

The className and style props also accept functions which receive states for styling. This lets you dynamically determine the classes or styles to apply, which is useful when using utility CSS libraries like Tailwind.

<Disclosure
  className={({ isExpanded }) =>
    isExpanded ? 'border-blue-500' : 'border-gray-600'}
/>

<Disclosure
  className={({ isExpanded }) =>
    isExpanded ? 'border-blue-500' : 'border-gray-600'}
/>

<Disclosure
  className={(
    { isExpanded }
  ) =>
    isExpanded
      ? 'border-blue-500'
      : 'border-gray-600'}
/>

The states, selectors, and render props for each component used in a Disclosure are documented below.

Disclosure#

A Disclosure can be targeted with the .react-aria-Disclosure CSS selector, or by overriding with a custom className. It supports the following states:

Name	CSS Selector	Description
`isExpanded`	`[data-expanded]`	Whether the disclosure is expanded.
`isFocusVisibleWithin`	`[data-focus-visible-within]`	Whether the disclosure has keyboard focus.
`isDisabled`	`[data-disabled]`	Whether the disclosure is disabled.
`state`	`—`	State of the disclosure.

Button#

A Button can be targeted with the .react-aria-Button CSS selector, or by overriding with a custom className. It supports the following states:

Name	CSS Selector	Description
`isHovered`	`[data-hovered]`	Whether the button is currently hovered with a mouse.
`isPressed`	`[data-pressed]`	Whether the button is currently in a pressed state.
`isFocused`	`[data-focused]`	Whether the button is focused, either via a mouse or keyboard.
`isFocusVisible`	`[data-focus-visible]`	Whether the button is keyboard focused.
`isDisabled`	`[data-disabled]`	Whether the button is disabled.
`isPending`	`[data-pending]`	Whether the button is currently in a pending state.

DisclosurePanel#

A DisclosurePanel can be targeted with the .react-aria-DisclosurePanel CSS selector, or by overriding with a custom className.

Name	CSS Selector	Description
`isFocusVisibleWithin`	`[data-focus-visible-within]`	Whether keyboard focus is within the disclosure panel.

Advanced Customization#

Contexts#

All React Aria Components export a corresponding context that can be used to send props to them from a parent element. This enables you to build your own compositional APIs similar to those found in React Aria Components itself. You can send any prop or ref via context that you could pass to the corresponding component. The local props and ref on the component are merged with the ones passed via context, with the local props taking precedence (following the rules documented in mergeProps).

Component	Context	Props	Ref
`Disclosure`	`DisclosureContext`	`DisclosureProps`	`HTMLDivElement`

This example shows a DisclosureGroup component that renders a group of disclosures. The entire group can be marked as disabled via the isDisabled prop, which is passed to all child disclosures via the DisclosureContext provider.

import {DisclosureContext} from 'react-aria-components';

interface DisclosureGroupProps {
  children?: React.ReactNode,
  isDisabled?: boolean
}

function DisclosureGroup({children, isDisabled}: DisclosureGroupProps) {
  return (
    <div style={{display: 'flex', flexDirection: 'column'}}>
      <DisclosureContext.Provider value={{isDisabled}}>
        {children}
      </DisclosureContext.Provider>
    </div>
  )
}

<DisclosureGroup isDisabled>
  <MyDisclosure title="How to make a return" >
    Details about returning items
  </MyDisclosure>
  <MyDisclosure title="How to cancel an order" >
    Details on canceling an order
  </MyDisclosure>
</DisclosureGroup>

import {DisclosureContext} from 'react-aria-components';

interface DisclosureGroupProps {
  children?: React.ReactNode;
  isDisabled?: boolean;
}

function DisclosureGroup(
  { children, isDisabled }: DisclosureGroupProps
) {
  return (
    <div
      style={{ display: 'flex', flexDirection: 'column' }}
    >
      <DisclosureContext.Provider value={{ isDisabled }}>
        {children}
      </DisclosureContext.Provider>
    </div>
  );
}

<DisclosureGroup isDisabled>
  <MyDisclosure title="How to make a return">
    Details about returning items
  </MyDisclosure>
  <MyDisclosure title="How to cancel an order">
    Details on canceling an order
  </MyDisclosure>
</DisclosureGroup>

import {DisclosureContext} from 'react-aria-components';

interface DisclosureGroupProps {
  children?:
    React.ReactNode;
  isDisabled?: boolean;
}

function DisclosureGroup(
  {

State#

DisclosureGroup provides a DisclosureState object to its children via DisclosureStateContext. This can be used to access and manipulate the disclosure group's state.

Hooks#

If you need to customize things further, such as accessing internal state or customizing DOM structure, you can drop down to the lower level Hook-based API. See useDisclosure.
