This can certainly work, though seems less flexible in the long run as to update categories you have to go into the code base and make the change there, rather than have a configurable set in a table.

But even with this, it's quite possible, but again, you're necessarily hard coding the selection instead of drawing it from a table. In you category navigation, you offer the user the ability to select on of Box, Cover or Poster, and then use gather them in the appropriate controller with pins = Pin.where(:category => params[:category]) for example (depending on how you actually get the user's desired category).
