dropAll

static dropAll = e

DragAndDrop.dropAll is used to drop all objects as if it was drop for every dragList item, but in add you can specify a drop_f function, that will be executed only in that case.

It's mostly used to drop all objects if cursor leaves page while dragging something to exclude unexpected behavior.

Example:

demo_body.addEventListener("mouseleave", DragAndDrop.dropAll});
