after upgrading from ST to ST 2.1 i've got a problem with my implementation of a simple
expandable list. On itemTap i used to toggle the hidden cls of the according div element. With ST it worked fine but on ST 2.1 there seems to be a problem. When the element is toggled to visible it is being shown, but the overall height of the item seems not to be adjusted and the following items are not moved downwards. Thus the new visible div element is being shown upon the next item.

Any suggestions?
