I was looking for a solution similar to google auto suggest where the user clicks or begins typing and a drop down appears, istock.com search field has it too.
don't worry about the Ajax part, I could design it myself, but if there's one already coded, I'd appreciate the time saving.
It also helps to re-use code on tight deadlines and code that's been used over and over, cross-browser bugs have been corrected.
I'll make my own and post it here if no replies in the next couple of weeks.
Bye!
