Telerik.Web.UI.Overlay.IsSupported = function ()
//By default overlay is enabled in IE only
We will not enable by default the iframe overlay in all browsers as it may have side effects. I tested the aforementioned script block and RadMenu worked as expected in FireFox. In Chrome the menu went behind the pdf iframe. However I think that in Chrome no html element can overlay the pdf iframe - I tried this without success:
<iframe src="my.pdf" style="position:absolute;z-index:1"></iframe>
It seems the pdf plugin is rendered outside of the html document and cannot be overlain by html elements.
