Menu
I was playing around with ASP.NET Web Parts which has a "drop down" div. It's all the way to the right of the page. When I click to bring it up, it goes off the window. Usually anything off the viewable area will trigger the bottom scrollbars. How is this possible?
Edit: It's Internet Explorer 8. Below is the markup with some context. The relevant one I think is id=WebPart_wp774658725VerbsMenu. By default it doesn't display. When you click on the td/span Verbs/span VerbsPopup (it could be any), it shows the "dropdown". In Developer Tools I don't see any JavaScript attached to those elements, but if I debug it I see it running some.

It is indeed the createPopup method that does the trick. It's a proprietary method in Internet Explorer.
