[jQuery] QuickSearch with a twist

[jQuery] QuickSearch with a twist


I need to use jQuery to emulate some functionality found in iTunes and
Quickbooks. These programs allow users to begin typing the name of a
record, and scroll a multiple-select box as the user types to
automatically highlight the relevant record. (For example in <a
href="http://paul.malan.org/images/tmp/itunes-scr.jpg">this
screenshot</a> I typed "pin" and iTunes automatically selected
"Pinback" in the Artists box.)
I found Rik's <a href="http://rikrikrik.com/jquery/
quicksearch/">QuickSearch plugin</a> which does something quite
similar, but I'll admit I'm not yet clever enough to replace his "show/
hide" behavior with a "scroll-to and select" behavior, either using a
select box or just div's.
Have any of you done something like this? What would be a good way to
approach this design element?
Thanks...
