Cancelling a drag and drop

Cancelling a drag and drop


Hi
Do you know a way to cancel a droppable action?
For example i put a div droppable in other one like a view on a
picture.
<div id="containerView">
<div id="droppable"></div>
</div>
but i want to stop the dragging when the mouse goes out of the
CointainerView.
The "containment" property is useless in my case. My droppable obejct
is bigger than ContainerView.
So there is a way to cancel or to disable temporaly the dragging
action.
Thank to you.
