I've got the following menu-structure
Main-menu
- level 1
level 2
level 2
level 2
- level 1
When I click a level 1 menu-item, the corresponding level 2 menu-items are displayed in de left sidebar. So far so good. But when I click a level 2 item, all level 2 menu-items disappear. I need to keep these menu-items being displayed in de sidebar. Is this possible?
