I have a device based RM setup. My RM sidebar nav list on the left includes 10 main manufactures and their devices listed below them. A lot of my categories under those main categories are coming up with 50+ devices. So if i click on a device category in that list it still shows all the sibling devices in that category making the list very long. Since the page loads to the top, if you have something at the bottom it makes it almost unusable. Is it possible to only show the parent and child categories in the RM sidebar with a specific category selected?
