Thanks for writing back.
One of our concerns about using grouping in the popup of RadListPicker is that when you tap on group headers another popup would open making it two simultaneously on the screen. This is not a good practice and therefore we opted for putting RadDataBoundListBox within the popup instead of RadJumpList.
A possible way of implementing similar behavior would be to use RadJumpList
with grouping and put it on a separate page which is opened when selection has to be made. This will allow you to use grouping and also allow for tapping on group headers for faster navigation.
