Jquery Sortable withset placeholder forever

Question

Hi!
I hope someone can help me.

My Problem:
I have 2 sortable UL's.
<ul id="k1"> and <ul id="k2">

When i drag a li from k2 into k1, the k2 ul collapse (coz there is one li missing now).

Is it possible to say
-> When draggable start, insert a non draggable clone into the k2?

and

If drag successful
-> Put LI into k1

if not
-> Put LI Back to the k2 and remove the clone

kind regards Peter
