Drag and drop select option

Hi
How do I drag and drop a option from a select list? I tried to search
for this problem... read few references... but did not find anything
yet... can this be done using JQuery...
I am trying to arrange the list items in a sequence, so I want to drag
them from one list to another..
Pls let me know how this can be done... I am using IE 6. and latest
version of JQuery.
thanks
