I've run into a bit of a road-block with my Ubercart setup. I'd like to be able to drill-down on sub-categories of the catalog, and have some indication of where I am so that I can style screen elements appropriately. I think I'm missing something obvious, but not really sure what it could be.
Here's an example of what I'm trying to do. I've got categories:
Kitchen
-- Amana
-- Fridges
-- Washers
-- Stoves
-- GE
-- Stoves
-- Knives
-- Kitchenaid
-- Blenders
-- Toasters
Below each of the above subcategories is the final product list. There are 2 things I'm trying to do:
1. When I'm at, say, Knives, I should have some indication in my page that I'm still under the Kitchen parent so that I can keep this list element highlighted. I should also be able to highlight GE.
2. I need to be able to click on Stoves and find only GE Stoves because I've arrived at Kitchen -> GE -> Stoves, vs. Kitchen -> Amana -> Stoves. I would have thought that this parent-child relationship would be maintained in the Catalog, but it does not seem to be the case. Each sub-category is considered to be a root element, and only the immediate parent is known.
I would greatly appreciate any advice on this. I've scoured the forums and google, and found a number of comments related to the 2nd issue above, but none with a real solution 
I'd be happy to do this with a view, and do the taxonomy walk, but I want to keep it as simple as possible so that people without technical skills can still manage things easily.
Thanks for any and all suggestions.
