I was just running the examples from Phil's book

Anyway, I'd like to understand how to write a widget that presents two 
(or more) <select> tags, related one to another (for instance, State and 
City) either dynamically via xmlhttp or by reloading the page.

Where can I find more 'custom' widgets, in particular dynamic ones?

Thanks
