[support] Adding custom menus as submenus

[Krister Ekstrom]

Hi,
I want to add a custom menu i have created called "the person" and later
another menu called "the business" as an expandable sub menu to "primary
links".
I tried adding the menu as a new menu from the "menus" page, but then i
couldn't get it expandable/colapsable and i could move it by placing
weight on it, but not where i wanted it, which is under primary links.
Is this something i'll have to have a completely different menu making
module for or can you do it with the existing module? I want to be able
to expand menus by clicking the parent link so as to avoid clutter.
Did that make sence?
Any help much appreciated.
