Taxonomy Admin Search

Description

This plugin injects a small search box at the top of taxonomy metaboxes (the checkbox lists) on the post edit screen. It only appears for taxonomies that have more than 5 terms to avoid clutter.

Search queries are performed via AJAX and the checklist is filtered client-side for a quick, responsive experience.

Installation

Upload the taxonomy-admin-search folder to the /wp-content/plugins/ directory.
Activate the plugin through the ‘Plugins’ screen in WordPress.
Edit a post that uses a taxonomy with more than 5 terms and the search box will appear above the taxonomy metabox.

FAQ

Will this plugin change term assignments?: No. It only shows/hides existing checklist items. It doesn’t add, remove, or modify terms.
Can I change the threshold of 5 terms?: Not from the UI yet. You can change the threshold by editing the plugin source where intval($count) > 5 is used.

We’ve been facing challenges assigning terms to posts and products due to the overwhelming number of terms. This plugin offers an excellent solution by adding a search bar whenever there are more than five terms, making it easy to search and assign terms efficiently. It saves a significant amount of time.
