Layout

Name	Type	Description
`slot`	`string \| null`	A slot name for the component. Slots allow the component to receive props from a parent component. An explicit `null` value indicates that the local props completely override all props received from a parent.

Button#

Show props

`form`	`string`	—	The `<form>` element to associate the button with. The value of this attribute must be the id of a `<form>` in the same document.
`formAction`	`string`	—	The URL that processes the information submitted by the button. Overrides the action attribute of the button's form owner.
`formEncType`	`string`	—	Indicates how to encode the form data that is submitted.

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.
