hi sorry to bother you guys again, but for the timetable easy ui, is there anyway that the items in div class left (div blocks for english, math, etc.) be generated and created from a database?

Hi i am new in the world of programming and jquery and i was trying to implement the timetable easyUI system that was provided in the tutorials and demo. But i realised that once you dragged a div element into the drop box, you cannot remove it. Is there any code that i should know of to remove the appended element and delete it from the timetable? As said previously i am a noob in this... thanks for any clarifications or help provided.
