In an answers community, a category group provides one or more categories that help organise questions for easy browsing.

If the category group contains a hierarchy, only the first-level categories display on the Answers tab. For example, if you're a computer manufacturer you might create a Products category group for your Products community that has four categories: Performance Laptops, Portable Laptops, Gaming Desktops, and Enterprise Desktops. Community members can choose one of the categories to assign to a question. Administrators create the category group and categories and then associate the category group with their answers community. An administrator defines separate categories for their ideas and answers communities.
