		 *	- The value submitted with the form is the hidden value (ex: CA),
		 *	  not the displayed value a.k.a. label (ex: California)
		 *
		 *	Enhancements over plain HTML version:
		 *	- If you type in some text then it will filter down the list of possible values in the drop down list.
		 *	- List can be specified either as a static list or via a javascript function (that can get the list from a server)
