You can add an interal link quite easily, it’s the same approach you use for adding custom items, you simply exclude a callback function and set the menu slug to the applicable URL, here’s an example. add_action( ‘admin_menu’, ‘add_user_type_link’ ); function add_user_type_link() { add_submenu_page( ‘users.php’, ‘Customers’, ‘Customers’, ‘edit_users’, ‘users.php?role=customers’ ); } Adjust the code as … Read more
