I want to remove or hide Categories / Tags submenu under Posts in the Admin Menu. I know this works with the themes submenus:
remove_submenu_page( 'themes.php', 'widgets.php' );
The same doesn't seem to work for posts unfortunately:
remove_submenu_page( 'edit.php', 'edit-tags.php' );
I'm using the admin_menu action:
add_action( 'admin_menu', 'function_call' )
Do I need to add something else?
