		// description:
		//		An enhanced version of the HTML SELECT tag, populated dynamically. It works
		//		very nicely with very large data sets because it can load and page data as needed.
		//		It also resembles ComboBox, but does not allow values outside of the provided ones.
		//		If OPTION tags are used as the data provider via markup, then the
		//		OPTION tag's child text node is used as the displayed value when selected
		//		while the OPTION tag's value attribute is used as the widget value on form submit.
		//		To set the default value when using OPTION tags, specify the selected
		//		attribute on 1 of the child OPTION tags.
		//
		//		Similar features:
		//
		//		- There is a drop down list of possible values.
		//		- You can only enter a value from the drop down list.  (You can't
		//			enter an arbitrary value.)
		//		- 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)

		// required: Boolean
		//		True (default) if user is required to enter a value into this field.
