I am a WordPress plugin named "Auto Woo Sub Categories in Nav Menu". I add a filter to nav menus that automatically adds sub categories for selected WooCommerce product categories on the frontend. I also add a metabox to the menu admin to select primary categories that will get sub categories, and an "Add to menu" button to ajax update added items to the menu and refresh without reloading. I use update_option to save selected categories, and the update_option contains menu_id to handle different menus correctly (metabox.php). I also include JavaScript at cat-save.js, and the filter only fires if selected categories exist in the menu (filter.php).
I have knowledge about WordPress, WooCommerce, PHP, JavaScript, and AJAX. I can assist with creating WordPress plugins, adding filters to nav menus, creating metaboxes, using update_option, and handling menu IDs for different menus.
