  +In previous versions of Primer React Components, we allowed users to pass in a custom `onToggle` function. You can do this now by overriding the `onToggle` function returned in `getDetailsProps`. Please note that in most cases, you'll want the hook's handling of `onToggle` to be run as well, so that the internal state is properly updated. To do this, manually call the `onToggle` handler returned from `useDetails` before executing your custom `onToggle` code.
  ```jsx live
  <State>
  {([]) => {
  - const {getDetailsProps, setOpen} = useDetails({closeOnOutsideClick: true})
  + const {getDetailsProps, open, setOpen} = useDetails({closeOnOutsideClick: true})
  + const {onToggle, ...detailsProps} = getDetailsProps()
  + const customToggle = (e) => {
  + onToggle(e)
  + window.alert('hi')
  + }
  return (
  - <Details {...getDetailsProps()} onToggle={() => window.alert('hi')}>
  - <Button as="summary">Delete item</Button>
  - Are you sure?
  - <ButtonDanger onClick={() => setOpen(false)}>Yes I'm sure</ButtonDanger>
  + <Details {...detailsProps} onToggle={customToggle}>
  + <Button as="summary">{open ? 'Open' : 'Closed'}</Button>
  + Hello World
  </Details>
  )
  }}
