jQuery Menu border question

jQuery Menu border question

Hi.  I'm loving the jQuery menu plugin.  I would like for the main menu to have no border, but all sub-menus (pop outs) to have a border.  I figured out I can remove the border by adding..

.ui-widget-content {
      border: 0px;
}

... to my CSS, so long as it is called after the remote jquery-ui.css is loaded.  While this does remove the border from the main menu, it also removes the border from all sub-menus.  Is it possible for me to have the border on the sub-menus only?

Thanks for any advice you can offer,
-Scott
