I have different group categories that I group together under a parent (see screenshot). For example - I have Location, Skill Level etc.
The problem is that these group parent categories don't make sense by themselves (on the AS example you have parent groupings that do make sense, like Business, Entertainment etc.).
I think an easy solution might be to be able to set a flag against a category called "Selectable" or something so that when it appears in the UI it will be disabled but show it's children.
Otherwise I am going to have stupid users with groups with Location and Skill categories etc.
Thoughts?
