I have attached screen shots and the address is www.martab.com. I have the 2 categories on my testing server not the live server.
From the attached shots: When I click on Equipment Rentals in the main menu it takes me to the product results page. On the product results page I have the side (accordion) menu that shows Purchase (category) and no sub categories then Rentals (category) with sub categories.
I was able to modify the main menu to show only rental subcategories and purchase subcategories in the drop down when the viewer is on the respective landing page.
What I would like to do is; When I click on a rental subcategory in the main menu and go to the results page I want to show only the rental category and rental subcategories in the side menu and not Purchases. Then only purchases when that category is selected.
