I have a scenario where I will have fixed options for an AutoCompleteBox that users will select from. Each option is broken up into a few different groups. Users will be allowed to pick as many options as they would like but I would like to visually present them with the list broken up by group. Basically, we are trying to enforce a standard set of tags that a user can select from. These tags will later be used in searching and filtering. In the attached image,I mocked up what I am looking to do. Is this possible? If not, are they recommended alternatives for handling this type of thing? Thanks in advance for any help you can provide.
