Each of the nested Families will belong to the appropriate Category, and the host Family will belong to Electrical Fixtures and include a Shared Parameter (Type, Text) that had a fixed value of "CTC". In Views that Fire Alarm, Communications must be turned off, the Category can be turned off as normal as long as Electrical Fixtures in on. In View in which we just want to turn off Electrical Fixtures, we add a View Filter that turns off all elements of that Category that do not have "CTC" entered for that Shared Parameter.
