How to Add Ajax Taxonomies Filter in WordPress Search
A new popup would appear and you will see category and any other custom taxonomy you may have on your site. You can add a label for the taxonomy. You can choose to hide empty terms. Lastly choose a display type for your taxonomy terms. You can display them in checkboxes, dropdown menu, or radio buttons. After selecting custom taxonomy, you can further fine tune your search form by adding custom meta fields just like you added taxonomy.
You can search by Category, Tag, Custom Taxonomy, Post Type, Post Date or any combination of these easily to really refine your searches – remove the search box and use it as a filtering system for your posts and pages. Fields can be displayed as dropdowns, checkboxes, radio buttons or multi selects.
When you enable a taxonomy filter, a section for choosing hidden taxonomy terms is displayed in user profile page and in term edit pages. In user profile page you can select (for each user) a list of taxonomy terms that are removed from hierarchical term taxonomies inside admin pages.
By default, all taxonomy terms are visible in the hierarchical term taxonomies sections inside admin pages. You can choose only from max 2 nested levels but all the children of a hidden term are automatically removed from admin pages. Keep in mind that the hidden terms are not searchable and filterable.
In edit term page you can select (for all users) if term should be removed (make hidden) from hierarchical term taxonomies inside admin pages.
