I think it's astoundingly bad UI to have identical options in more
than one place - but that's just my opinion.

Unless your Menu model is exceptionally complicated, is it *really*
worth the significant boost in both code and SQL complexity just to
support this (hopefully uncommon) edge case? DRY is great, but there's
a point of diminishing (if not negative) returns...

As to the technical side of the question, you'd want to use a real
join model (with has_many :through). How else could you keep track of
the position of the repeated items in each of the parent menus?
