# 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 takes care of applying the WAI-ARIA Accordion pattern automatically for the activator and the toggled content.
### Basic Disclosure

```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
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
### open
For controlled disclosure components, the open state. The `open` prop should be used
along with `onToggle` to create a controlled disclosure component.
### onToggle
Callback fired when the open state of the disclosure changes.
### transition
Set to 'none' to disable the default transition animation.
### MaybeResponsiveConditionalStyle
A type that represents a value that can be a conditional style. The conditions are based on the viewport size.
We highly recommend using the `Style` helper which simplifies the creation of conditional styles.

To learn more check out the [conditional styles](/api/checkout-ui-extensions/components/utilities/stylehelper) documentation.
T | ConditionalStyle<T, ViewportSizeCondition>
### ConditionalStyle

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

### conditions
The conditions that must be met for the value to be applied. At least one
condition must be specified.
### value
The value that will be applied if the conditions are met.
### ViewportSizeCondition

### viewportInlineSize

### ViewportInlineSize

'small' | 'medium' | 'large'
### DisclosureOpen

boolean | string | string[]

### 
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.
