You are confused about the MVC model.  You can access any model you
like in a controller and setup the data for both panes of the view.
What are the relationships between the various models (categories,
listings, sub-categories or whatever)?  Getting those right is
crucial.  If Category is a self referential model then it is important
to specify that correctly to save yourself a lot of work.  Google for
rails self referential models if you don't know how to do it.  If you
find yourself accessing category.parent_id in the code then you are
almost certainly not got it right.
