After you’ve been using your website for a little while you probably have some categories, tags, or custom terms you once used, no longer use, but don’t want to wade through. WP Term Manager allows you to hide these terms.
The settings can be found under Tools > WP Term Manager. Select which terms you want hidden and click “Save Changes”. That’s it!

WP Term Manager

WP Term Manager helps users clean up or hide terms for easier administration.
