Creating SubMenus

["Nicolas Raitman" <new_world radar com ar>]

Hi to all. I know how t create menus and menuitems, but suppose I want to
have the following structure.

Edit
> Font
> > Bold
> > Italic

Do you understand? How can I do this? I know that I cannot do it with the
ItemFactory, that's why I am doing it in the complex way, creating each
thing, but I could not find out how to create a sub menu.

Thanks a lot,
Nicolas
