Selectable Enhancements


I'm trying to add a few things to my selectable and was wondering if
someone could point in the right direction. Firstly i'm trying to be
able to be able to hold shift and select different items and have it
select the range between them.
Secondly i've got two lists and would like to be able to drag and
selection across both of them. There was one way i got this to work
which was put the two lists inside a div and then give that an id
which i loaded when initialising the selectable. This however broke
the ability to single click the items.
Thanks in advance for anyhelp you can give.
