Does anyone know how it's possible to produce an interface for checkbox selection like the one in Gmail? Namely, where you can hold down shift and click the first and last items in a list, and it'll automatically select all the ones in between. Is it possible with simple JavaScript without having to use AJAX or other fancy-pants technology...

PHP/AJAX: Say I have a form with 3 SELECT's - country, state/province, city. I'm looking for a something that will update the SELECT's from the server using AJAX if possible, but will also degrade to the non-AJAX version for people that have JavaScript disabled. Can anyone recommend a PHP library that can do that?
