You cannot assign a category to Advice and Counsel matters. Instead, the General page contains a Topic list which contains categories that apply to Advice and Counsel matters. Based on the topic that you select, additional fields may appear in a separate block on the General page. This block may contain required fields that you must complete before you can save the matter.
For example, many of the available topics are employment topics. These topics, such as Disability, Harassment, and Discrimination, are grouped together in a hierarchical drop-down list under Employment. Once you select a topic, such as Harassment, return to the General page to see if any required fields appeared that are related to Harassment and must be completed to save the record.
