This is probably something stupid easy, but I didn't see anything with a search.

I have an assembly drawing where I need to hide some components.  I usually do this through the hide/show Components tab in the Drawing View Properties.   [I know I could do this with a display state in the model, but I want to know why this isn't working right in the drawing.]

The assembly components are not all individual parts.  Some of the components are themselves subassemblies.  If I just pick on the subassembly, a subassembly part highlights, not the component (the subassembly entire).  If I try to use a right-click and a select/other, the subassembly component does not come up in the list.

How to make the program pick the first level components, and not pick the subassembly parts?
