Search functionality in 'taxonomy postbox' on edit post page

Question

• I created a custom taxonomy and added lots of terms.
• If I edit a page and want to add a certain term. It takes a lot of time to find the right one.

I would like to have the WP autosuggest search box.

How can I add the functionalitity that is already built on wp-admin/nav-menus.php?

Hope anyone can help me to build this.

Answer 1

Use jquery-ui-autocomplete, which is delivered with WP.

The add an ajax action that builds & filters the list.

You will have to deregister the post_categories_meta_box meta box and add your own, built on the core function post_categories_meta_box(), as the core box hasn't got any actions or filters.
