When you choose a menu item the menu is Highlighted (white as opposed to blue) but when you choose a tree item nothing changes so you know what tree item you choose, have I missed something in the code.

If you click on a menu item in the tree the text should become bold. You can change this to be whatever you want but the sample code makes it bold.

This is not the case in my code, and I can't find where this is happening can you tell me where this happens

In the CSS file there should be a
.selectedMenuItem
{
font-weight:bold;
}

I was missing it in my Code

Thanks
