Well, I don't know about Dojo, but I had to do this sort of things last
week (multiple forms on a page, with slide up & down, dynamically add
forms, update, display validation errors, etc). I started using Mootools
which I knew a bit, ran in a lot of issues, switched to jQuery which I
had no clue about and the thing was done in 10 lines of JS and 2 hours.

Of course HTML::FormFu powers it (it's a non-Cat app, made with mason),
but even without Catalyst, the simple FormFu + jQuery combination is
IMHO a killer. And I didn't even use the Forms plugin (which I should
probably have). I heard jQuery was crappy in some regards, notably
polluting the global namespace, which YUI takes care not doing IIRC, but
for what I had to do, using it was a real pleasure. It DWIM, easily,
and that's not so common.
