How to prevent autoclose menu after selecting option?

[Pawel-Zygmunt]

Do I need to control this with my own state and use this instead $menu.expanded, handle outside click and so on? Or is there an easier way ?

I think the best approach might be to allow control via the event itself (e.g. preventDefault or return false) - I'll have a play around and see what feels right.
