NOTE THE FOLLOWING ASSUMPTIONS:
----------------------------------------
1) All items that belong with a particular button bears
	the same name as the parent layer, plus suffix "Menu".
2) All of the parent items and menu items are laid out
	beforehand, e.g. - all items have the same width
3) Requires "layerControl.js"
