Assign menu to specific group of articles
My top menu consists of several groups of cms articles, like this:
Topmenu: section 1 | section 2 | section 3
When clicking a section, e.g section 1, I would like a submenu to appear in the left bar, like
article 1.1
article 1.2
article 1.3
How can this be achieved? Combining the parameter section=cms with a category doesn't seem to work.
Any suggestions?
