+				Which descendant elements to initialize as their respective widgets. Two elements have special behavior:
 				<ul>
 					<li><code>controlgroupLabel</code>: Any elements matching the selector for this will be wrapped in a span with the <code>ui-controlgroup-label-contents</code> class.</li>
 					<li><code>spinner</code>: This uses a class selector as the value. Requires either adding the class manually or initializing the spinner manually. Can be overridden to use <code>input[type=number]</code>, but that also requires custom CSS to remove the native number controls.</li>
