It is difficult to show the problem with a video. It is easier with a list:
1- created custom post type called “evento”
2- registered custom post type on standard categories with following code:
function add_categories_to_custom_post_type() {
register_taxonomy_for_object_type(‘category’, ‘evento’);
register_taxonomy_for_object_type(‘category’, ‘luogo’);
}
add_action(‘init’, ‘add_categories_to_custom_post_type’);
3- It works fine, I mean that I can add standard categories to custom posts. It works when I filter custom posts and categories with Big Grid Flex and other Newspaper theme functions
4- created menu including standard categories and set as Megamenu
5- Megamenu only show standard posts related to categories (custom posts related to same categories do not appear in Megamenu)
