2.5 (NEW!)

Minor bugfix:
* if the menu height is more than the page height the menu doesn't reposition it to let you scroll all the menu voices.

Minor features:
added a new param containment to let the urer choose either the containment is the window (default) or any other element that contains the menu; that's usefull if you want the menu adapt it's position related something else that the window.
usage: containment:"your element ID" as param on the menu call function.
