I'm not sure this is a good idea. I think the approach should be similar to a BScrollView instead, possibly even by using a BScrollView (which should be able to only show its scroll bars on demand, anyway). While BMenu could provide this functionality for convenience, that's not easily possible with the current API. The scroll buttons used by BMenu should become a thing of the past; they aren't really usable for larger menus.

as well as two new public methods:

EnableScrolling(bool enable)

As a general naming scheme, this should be:
SetScrollingEnabled(bool enable)
IsScrollingEnabled() const
