# JavaScript: HTML5 Drag and drop script
# param1 (WebElement): Source element to drag
# param2 (WebElement): Optional - target element for the drop
# param3 (int): Optional - Drop offset x relative to the target if any or source element
# param4 (int): Optional - Drop offset y relative to the target if any or source element
# param4 (int): Optional - Delay in milliseconds (default = 1ms) for dragging and dropping
# param5 (string): Optional - Key pressed (alt or ctrl or shilf)

Were anyone able to drag and drop in this site with above piece od code?
