i am trying to implement three features:

1.  a scrollable div containing image thumbnails

2.  that can be sorted by jquery isotope

3.  that when hovered over display a div on top of other elements and beyond immediate containers.

at the moment i can get either one or the other happening ie either the scrollbars show but then the hover state div is behind other elements, or i can get the hover state div in front of other elements but then the scrollbar does not display.
