flat list not working

hi,
just tried to selsect the flat list option and if it is activated the menu renders only the menu items in a list without any stlying at all. is this how it is supposed to work? i am not sure.
if i deactivate it the syle css3megamenu is displayed normal.
you can see it here:

is this the way the flat list should look and you have to apply all the styles in a spereate css-sheet manually?

thank you!

menu renders only the menu items in a list without any stlying at all

of course, that's why it is called "flatlist" !

the flatlist view should only be used in a subemnu to load another maximenu module to show some virtuemart categories for example.
