It's mine first post, so sorry for mistakes or repeating.
I'm creating some kind of program, which is used to create groups for school from the students list. For this I'm using GXT (Ext GWT) Drag and Drop list http://www.sencha.com/examples/pages/dnd/listtolist.html. When I copied this code, it works for me, but with one exception, there is no borders, no scrollbars etc., its just plain list in the middle of the page. I guess everything is done through css? Am I right?
