I have placed a menu in the sidebar and wondering if it's possible the menu's expand / collapse when you click on the category. So you can see the sub category’s under it.
For example: I got the category “Kenwood” and “Motorola” and for each category there are sub category’s “headsets” and “Battery’s” (if you click on a sub category you go the products).
I would like to hide these sub category’s until you click the category itself.
Is that possible?
