You can do most of this already with a Repeatable block element, and HTML::FormFu::Model::DBIC See the test files in the HTML-FormFu-Model-DBIC for examples, specifically: t/default_values/has_many_repeatable* t/update/has_many_repeatable* There's also support for a checkbox which deletes that row, if checked. I have an example Catalyst application, which also supports adding new rows by doing a round-trip to the server - but I'm not sure if it's working at the moment, and unfortunately I won't have time this week to look at it (and I'm on holiday next week) - but if you want a look at it after that, give me a shout. Btw, the HTML::FormFu::Model::DBIC documentation on cpan is horribly out of date. It's been improved somewhat in svn, but is still missing a lot.
