I am trying to make a drop menu with css (js.fiddle: http://jsfiddle.net/Zbv6f/6/) and I want the child drop element to appear underneath the parent, but it appears above it. I have set the z-index for the drop element to a lower value but it is not working. Even more confusing, I have an arrow made with css in the parent that does display above, with the same z-index.
Can anyone help me out here?
