Do you have a lot of categories and are sick of having a huge list in your sidebar? Want to highlight only a few of them to make your site easier to navigate?
While redesigning WordPress sites for our clients we kept running into this problem over and over. They had a huge list of legacy categories but only wanted to highlight a few of them. We wrote this plugin to allow them to select which categories to show and which categories to initially hide.
All categories are still accessible by a “see all” link at the bottom of the list.
Add the widget to your sidebar to make it live.
