Scrolling in draggable

Scrolling in draggable


Hi, there:
I have a question about scrolling in draggable. If I want to make drop
zone scrolling, and if the drop zone is the container of the draggable
element, I just need to set scroll option to "true" and scrolling
works.
If the drop zone is not the container of the drggable element,
scrolling does not work. This issue is common if the drop zone is the
sibling or not directly related to draggable.
Is it possible to make drop zone which is not the container of the
draggable scrolling?
Thanks,
Henry
