Categories are administrator-defined values that help organize ideas into logical sub-groups within a community. The View Category drop-down list on the Ideas tab allows users to filter ideas by category, and the Categories picklist on the Post Ideas page lets users add categories to their ideas. For example, if your ideas community has the focus “Improvements to our clothing line,” then you might set up categories such as “Shirts,” “Jackets,” and “Slacks.” Each organization has one common set of categories that can be added or removed from each community. An administrator defines separate categories for their ideas and answers communities.
