I want to put a second menu under the main menu, and I wish this second menu that contains in turn would open the submenu items in horizontal dropline. As de vo do? I attach a picture to show you how I wish it would open the submenu items as you can see in the dark.

But be careful that you do not want to open up in this way from the main menu, but I want under the main menu where there is a ccording to the menu at the middlemenu or topmenu2 you aprino the submenu.

know what I mean?

please is urgent!

Hi

I believe this position is called "middlemenu". Please simply publish Menu module in this position but set it to show from a second level. This way with every menu item its submenu will be shown there.
