Is there anyway to limit the categories available for each attribute set? I'm using a multi-vendor marketplace extension, and when a user wants to list a new product, they have to sift through checkboxes of every category available. (There are a lot on my site...)
At the very least, is there anyway to make the category list collapsible? Like Root > Sub > Sub > Sub collapses into just Root automatically so that it's easier on the eyes and easier to find the category they wish to list the product in?
