How can I use the CSS Skin File to style only the first level nodes of the TreeView? I have tried styling rtTop and rtFirst, but those only style the first node of each level of the first branch or the very first node of the whole tree. In addition, how can I have the lines show only on the lower level nodes and NOT for the first level?
I've attached two images to illustrate my request. The first is the TreeView as it appears by default and the second is how I would like the TreeView to be styled (first level nodes that have a background style and no lines connecting them).
Any help with this would be greatly appreciated.
