Need help with category listings in my xcart store. I have a horizontal menu for my top level categories. I have modified my store to display subcategories in the left bar for corresponding top categories. Problem is that when you click one of those subcategories, the menu disappears, since there are no sub sub categories or 3rd level categories to display. I would like those corresponding sub categories to remain displayed as you move through them as well as viewing product detail pages. Easy task, I'm just not 100% clear on necessary commands.
