Sorry, I'm very new to sencha, so this question may have a very simple explanation.

I've added a background to a panel in sencha touch using the 'cls' config option and a CSS setting for x-panel-body, and it seems that when I add new items the background is included/repeated for each item. Does anyone know a way to make the items overlay the background of the full panel without each item having a separate copy of the background?

Thanks very much for any ideas
