As we are missing a mobile component for drop down lists i'm trying to make a simple one of my own. There is a button and a text area, and i'd like the button to pop open a new window and grey out the current view, then show a list of the possible values. What top level uicomponent should i use for the popup? a view doesn't seem to be able to be easily overlayed on top of another view.
I just released a beta version of the Flextras AutoComplete component for mobile, which includes a mobile optimized DropDownList.

With regards to your specific problem, I'm not sure. Our current implementation is a traditioanl DropDownList; and uses a popUpAnchor and skin state changes to open the drop down.
