DataTransfer: addElement() method

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The DataTransfer.addElement() method sets the drag source to the given element. This element will be the element to which drag and dragend events are fired, and not the default target (the node that was dragged).

Note: This method is Firefox-specific.





The Element to set as the drag source.
