Customize DrillDown.html

Hi,

This standard DrillDown button just shows item's picture and its
description. I like to change it to show the picture at left side (about 40%
of the width) and Item price with UOM and description in 2 lines at the right
side. I would appreciate all helps to me on the "innerHtml". I can figure out
getting price and UOM, but don't know html syntax for the layout.
