Designer and menuBar with menus and sub-menus.

Hi all,
I am a new user of vaadin. I try to build a dasboard with a menu bar using Designer. And I can’t do this starting with a classical layout (Heder, content, outline eand footer). Some body can tell me how to process.

It’s completely diffrenet from using Application.e4xmi in Eclipse and I am a litlle bit lost.

Tanks a lot
