With the default WordPress installation you can display a list of categories in the side bar. Sometimes you do not want to show every category however. You may be designing a custom page, where you only want the subcategories showing, or some themes use a custom category like “featured” to show only the posts that are in this category on the main page. You don’t usually need or want this category showing in the side post, it is just “clutter”
There are many plug-ins that can provide you with a customized category listing, however I have found from experience, that you can spend way too much time downloading, installing, and repeating until you find one that suites your site.
There is an easier way to exclude specific categories from your Category list.
