Silverlight and "z-index"

I have a Silverlight clickable map and a sliding panel (jquery) that drops down. Despite giving the panel a high z-index, it still slots behind the silverlight app.

You can see this here: Problem in action...

To activate the sliding pa开发者_运维问答nel, click "Translate" at the very top left of the window.

Is there anyway to let such a "sliding panel" cover up my silverlight app?

You will need to set the Silverlight plugin object to be windowless. Take note of the limitations listed on that page, as setting the plugin to windowless comes at a cost (e.g. performance).
