I wondered if you can do this to allow for custom icons for the panel menu. I know I can specify individual images for the icon but I want to use one large image and then use the background position to bring it into focus. This method is known as CSS sprites.
In the stylesheet I set a background image on the span. I've already done this with the rich:tree componenet, just wondering if I can do the same to panelMenu.
Any advice gratefully welcome.
