Unless I have missed something, it seems that it is not possible to set permissions or visibility on the top level Forum or Solution Categories/Folders
For example, I would like to create a Solution Category visible only to agents. Using the current configuration I can create folders under the solution category and assign specific permissions to those but not to the parent category itself. Presumably Customers viewing from the portal would then see a Category Title without any apparent content (empty), but it would be preferable that they see nothing at all.
Or would the Parent category automatically be hidden if none of the child folders/topics are actually visible?
