I'm talking about the style of the repeater itself, not of the elements inside it. It can have a background but it can not have a drop shadow.
By moving dynamically I mean when an event occurs. For example when some other object resizes to put on its OnResize event an action to move the repeater. Now, if one wants to do this, he has to group the repeater and move the group. I think it would be easier if the repeater itself could be moved and no grouping necessary.
At least for me, these two options would be very useful. I prototype a lot of drop-down menus that need drop shadows and, sometimes, need to be repositioned dynamically.
