When discussing forein key support, it was mentioned that automaticaly
generating select tags for tables with millions of rows would be a
problem, which I agree, of course. 
Now I have exacly that problem :) Not with millions but with enough
hundreds to be annoying.

Since those hundreds can be divided into "categories" what I would like
to present the user would be a select tag with a category, and when the
user selected one gategory, the other select tag (the one with the few
hundred) would presnt only a subset acording to the category the user
chose.

Any idea how that could be acomplished ?
Maybe with the help of some javascript ? I think when we have a table
with a sortable field when selecting the sort order it must have a
onChange event that redisplays the page with the new Order. It could
perhaps be something like that ...
