## Code

```php
add_action( 'restrict_manage_posts', function ( $post_type ) {
    if ( ! post_type_supports( $post_type, 'author' ) || ! current_user_can( 'edit_others_posts' ) ) {
        return;
    }

    wp_dropdown_users( array(
        'name'                    => 'author',
        'show_option_all'         => 'All authors',
        'selected'                => isset( $_GET['author'] ) ? absint( $_GET['author'] ) : 0,
        'capability'              => array( 'edit_posts' ),
        'hide_if_only_one_author' => true,
    ) );
} );
```

## Notes

WordPress already understands the author filter; this snippet only adds the dropdown.
