hard to say without seeing what you have in mind...
how many menu items are there? aligned vertically or horizontally? evenly spaced out over the menu, or top or left justified? Are the menu items sprites? text objects?
do the menu items need to be pinned to the menu so it can slide on or off the screen?
how are the menu items sorted? is there a sequence they need to be in?
It would help if you could post a sample project with a general idea of what you want.
it doesn't make much of a difference if the items are created at runtime or not.
