# Disclosure

Disclosure is an optionally controlled component used to put long sections of information under content blocks that users can expand or collapse by pressing an activator. The activator can be specified as children using an action component (`Button`, `Link` or `Pressable`) or `Checkbox` component. The content blocks can be specified as children inside a structure component (`View`, `InlineLayout`, `BlockStack`, `Grid`, etc.).

The library automatically applies the [WAI-ARIA Accordion pattern](https://www.w3.org/WAI/ARIA/apg/patterns/accordion/) to both the activator and the toggled content.

```tsx
import {
  reactExtension,
  Disclosure,
  Button,
  View,
} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(
  'purchase.checkout.block.render',
  () => <Extension />,
);

function Extension() {
  return (
    <Disclosure>
      <Button toggles="one">Toggle</Button>
      <View id="one">Content</View>
    </Disclosure>
  );
}

```

```js
import {
  extension,
  Button,
  View,
  Disclosure,
} from '@shopify/ui-extensions/checkout';

export default extension('purchase.checkout.block.render', (root) => {
  const disclosure = root.createComponent(Disclosure, {}, [
    root.createComponent(Button, {toggles: 'one'}, 'Toggle'),
    root.createComponent(
      View,
      {border: 'base', padding: 'base', id: 'one'},
      'Content',
    ),
  ]);

  root.appendChild(disclosure);
});

```

## DisclosureProps

### DisclosureProps

### defaultOpen

value: `MaybeResponsiveConditionalStyle<DisclosureOpen | undefined>`

  - MaybeResponsiveConditionalStyle: T | ConditionalStyle<T, ViewportSizeCondition>
  - ConditionalStyle: export interface ConditionalStyle<
  T,
  AcceptedConditions extends BaseConditions = Conditions,
> {
  /**
   * The default value applied when none of the conditional values
   * specified in `conditionals` are met.
   */
  default?: T;
  /**
   * An array of conditional values.
   */
  conditionals: ConditionalValue<T, AcceptedConditions>[];
}
  - DisclosureOpen: boolean | string | string[]
For uncontrolled disclosure components, the default `open` state on the initial render.

It's possible to specify a boolean value, a string value, or an array of string values:

- `true` will expand all content
- `false` will collapse all content
- `string` will expand the content with the matching `id`
- `string[]` will expand the content with the matching `id`s

### onToggle

value: `(open: string[]) => void`

Callback fired when the open state of the disclosure changes.

### open

value: `DisclosureOpen`

  - DisclosureOpen: boolean | string | string[]
For controlled disclosure components, the open state. The `open` prop should be used along with `onToggle` to create a controlled disclosure component.

### transition

value: `"none"`

Set to 'none' to disable the default transition animation.

### ConditionalStyle

### conditionals

value: `ConditionalValue<T, AcceptedConditions>[]`

  - ConditionalValue: export interface ConditionalValue<
  T,
  AcceptedConditions extends BaseConditions = Conditions,
> {
  /**
   * The conditions that must be met for the value to be applied. At least one
   * condition must be specified.
   */
  conditions: AcceptedConditions;
  /**
   * The value that will be applied if the conditions are met.
   */
  value: T;
}
An array of conditional values.

### default

value: `T`

The default value applied when none of the conditional values specified in `conditionals` are met.

### ConditionalValue

### conditions

value: `AcceptedConditions`

The conditions that must be met for the value to be applied. At least one condition must be specified.

### value

value: `T`

The value that will be applied if the conditions are met.

### ViewportSizeCondition

### viewportInlineSize

value: `{ min: ViewportInlineSize; }`

  - ViewportInlineSize: 'extraSmall' | 'small' | 'medium' | 'large'

Use the Disclosure component to simplify the user experience and reveal interfaces only when the customer requests it. It also demonstrates how a combination of inline and block layout components can improve the readability of information. By employing these strategies, users can easily scan and comprehend the content, making for a better user experience overall.
