How to have a draggable always on top?

How to have a draggable always on top?


Hi there,
I have some draggable windows on my page. Active windows have a z-
index of 300, passive ones 250. Now I have another draggable in one of
these windows and want to drag&drop it into another one (without a
clone). This works fine when I start to drag from a window with z-
index 300. But when I start to drag from a passive window, the
draggable vanishes behind the active one as it seems to have a lower z-
index. How can I fix this? The attribute zIndex doesn't wort, neither
with nor without a clone.
Regards
Eric
