 ## `timeout`
 
 The `<Count>` component displays a loading indicator after 1 second. This is useful to avoid displaying a loading indicator when the count is retrieved in a few milliseconds. You can change this delay by passing a `timeout` prop.

+## `sort`

+If you want to customize the sort options passed to `getManyReference` (for instance because your relation table does not have an `id` column), you can pass a custom `sort` prop:

 ## `target`
 
 The `target` prop is required and must be the name of the field in the related resource that points to the current one. For instance, when fetching the number of comments related to the current post, if a comment relates to a post via a `post_id` foreign key, you must set the `target` prop to `post_id`:
