I think what you are really looking for is a way to crop the shadow even with an edge of the element. You should be able to do this with overflow: hidden. So, supposing each LI had a box shadow, you could set overflow: hidden on the UL, and then give the UL enough padding on the other three sides so that the shadow is not clipped there.
