Just a little widget that adds in some useful functionality that WordPress (oddly enough) doesn’t include stock … listing almost all of your categories. Say, for example, you have a utility category entitled “Events,” and you want to display a list of all your site’s categories, but don’t want “Events” to display in that list. Instead of hard-coding a list into a text widget, just use this!

Almost All Categories Widget

This widget will let you display a category list in your sidebar, excluding any categories that you would like.

A simple plugin that displays a list of all categories except those selected in widget preferences. Unlike other similar plugins like “Almost All Categories Widget”, Categories but exclude uses the latest version of WordPress Widget API, which is multi-widget, which lets you use the wigdet more than once. Mostly, I created the plugin to use it with the plugin “WPML” along with “Widget Logic” to use the same widget for each language.
This will allow you to create a custom category list which will show the categories you want, and will hide the categories you do not want. For example, say you have a particular category you don’t want to be displayed named “Announcements”. You can use this plugin to display all of your other categories, except the category “Announcements”. You are not limited to just excluding one category; you can exclude multiple categories.
