Is it possible to add all categories/subcategories links automatically to WP menu from WooCommerce plugin? I have many categories (20) and even more subcategories (100+) and I need them to be shown in the main menu at the top, in a hierarchical way. I have tried from "Appearance->Menu" section to select all the categories at once in the menu, but they were all messed up, no hierarchy at all. Is there a solution to avoid inserting all the categories/subcategories manually as menu items?
