title: How to use jquery-ui selectmenu extension methods(_renderItem, _renderMenu etc)
body: <p>The JQuery-UI selectmenu widget has some extension methods that can be used to customize rendering/styling of the dropdown select menu.
  From the <a href="http://api.jqueryui.com/selectmenu/#methods" rel="nofollow"> api docs </a>, the following widget extension methods can be used to customize the menu:
   - _renderItem( ul, item )
   - _renderMenu( ul, items )</p>
  
  <p>What i want to achieve is, overriding the above extension methods for just one instance of the selectmenu widget, and not at a global level.
  The <a href="http://learn.jquery.com/jquery-ui/widget-factory/extending-widgets/" rel="nofollow">widget factory docs</a> does have example about extending a particular instance of a widget(example is at the bottom of this page), but haven't had any success in applying that to the selectmenu extension methods. 
  Any insight for this issue is much appreciated.</p>
