Custom classes for WpMenuItems don't show up

[drewbaker]

If I try to add the category ID of a menu item as a menu item class, it doesn't end up on the final menu item.

This doesn't work:

     function add_dev_id_to_nav_items($nav_item_data){


         if ( isset($nav_item_data['id']) ) {
             // get full nav item
             $object_type = get_post_meta($nav_item_data['id'], '_menu_item_object', true);
             $object_id = get_post_meta($nav_item_data['id'], '_menu_item_object_id', true);

             if ( $object_type == 'category' ) {
                 $nav_item_data['classes'][] = 'category-id-'.$object_id;
             }

             //var_dump($nav_item_data); die;
         }

         return $nav_item_data;
     }
     add_filter('rez_serialize_nav_item', 'add_dev_id_to_nav_items');

@drewbaker Are you still running into this issue? Just checking before diving in - at first glance, we might have found a Vue-ier way of doing it since then. Thanks!

Yeah this was on Story Attic, the last site I built. Would love to improve the menus, always seems finicky and manual to get the right classes on them (specially when it comes to News, categories or blog posts).
