JQuery Sortable List with

JQuery Sortable List with


I am having an issue trying to get only selected items to be connected
with another sortable list while keeping them all movable.
For example I have two sortable lists.
LIST 1
Item A
Item B
Item C
LIST 2
Item D
Item E
Item F
I want all items to be sortable on either list execpt for Item A.
Item A i want to be able to move up and down only in its parent list
(LIST 1).
I cannot achieve this. The containment property will apply to all
items in that list and the cancel property will make that item
unmovable.
Any ideas on how to achieve this?
Thanks.
Tom
