Hrm ... when I added plus/minus images, I added <img> tags within the
list items. I made the list items position:relative and that way I
could use position:absolute for an <img> and a <label> within the list
items. Then, with prototype, you can use the up() function to figure
out what list item you're within.
But, in your case, the best I can think of is to maybe float a <div>
element over the plus/minus background image?
