I've installed the oxygen theme for my website (a diy online magazine). My problem is that I have 6 main topics, with several subcategories. For each main topic I will like to have a different menu. For example, when you click the home decor section displayed in the top bar menu, you'll see a side bar with living rooms, bedrooms, bathrooms, a.s.o. For DIY projects, the side menu displays diy for kids, fashion diy, handmade e.s.o.
PS: oxygen theme allowed to create 3 different menus (top, side and bottom). I know how to do all this. The thing is that all bar menus are the same for all 6 main topics and I want a common top bar, but different side bar. The bottom one is not important.
Thanks for your support!
