# DisclosureGroup



## Expanding

Use the `defaultExpandedKeys` or `expandedKeys` prop to set the expanded items, and `onExpandedChange` to handle user interactions. The expanded keys correspond to the `id` prop of each `<Disclosure>`.

```tsx
import type {Key} from 'react-aria-components';
import {DisclosureGroup} from 'vanilla-starter/DisclosureGroup';
import {Disclosure, DisclosureHeader, DisclosurePanel} from 'vanilla-starter/Disclosure';
import {useState} from 'react';

function Example() {
  let [expandedKeys, setExpandedKeys] = useState(new Set<Key>(['system']));

  return (
    <DisclosureGroup
      /*- begin highlight -*/
      expandedKeys={expandedKeys}
      onExpandedChange={setExpandedKeys}>
      {/*- end highlight -*/}
      <Disclosure id="settings">
        <DisclosureHeader>Settings</DisclosureHeader>
        <DisclosurePanel>Application settings content</DisclosurePanel>
      </Disclosure>
      <Disclosure id="preferences">
        <DisclosureHeader>Preferences</DisclosureHeader>
        <DisclosurePanel>User preferences content</DisclosurePanel>
      </Disclosure>
      <Disclosure id="advanced">
        <DisclosureHeader>Advanced</DisclosureHeader>
        <DisclosurePanel>Advanced configuration options</DisclosurePanel>
      </Disclosure>
    </DisclosureGroup>
  );
}
```
