Is it possible to have a drop down box (validate, java, something?) that
will highlight an entire row?

For instance,
If Column A is set for three choices, 1 2 or 3, can i have the corresponding
row highlighted a color for each?

I'm great with validation drop downs, but i don't know a lot about buttons
and such. I believe it would be easier and more user friendly if someone
could tell me how using a button or control.

Thanks,
Jacob
