title: Rendering the elements of a GXT RadioGroup or CheckBoxGroup in multiple columns?
body: <p>I am looking for a way to render the elements of a GXT (GWT-Ext) RadioGroup or CheckBoxGroup in a layout other than a single column (Orientation.VERTICAL) or a single row (Orientation.HORIZONTAL).  I see that <a href="http://www.extjs.com/deploy/dev/examples/form/check-radio.html" rel="nofollow noreferrer">in ExtJS 3.0, RadioGroups and CheckBoxGroups are easily rendered in multiple columns</a>.  However, the configuration doesn't seem to be accessible in GXT.  Is there something I'm missing here?  If there is no "simple" solution, is there a way to write a custom renderer for a RadioGroup or CheckBoxGroup?</p>
