Solution for this sortable need


Hi, i'm using .sortable() on 2 connected lists. I need to dynamically
set/unset items that are sortables. How can i archieve this ?
I tried:
return false on start callback.
.draggable("disable") on the items
doing ul.sortable({ cancel : '.theitemsclass'}) (gives error)
.data to change "options"
Is there anyway i can modify the options which i first used ?
Please i can't think of a solution to this.
