Re: Prefill a checkbox with JQuery plugin
No idea myself. You can ask in Irc to jonnyb or robertplummer (they are the exports in Jquery): they were the ones who share their knowledge with Jquery in tiki, that I took to write my contributions at the doc. page about Jquery.
Please, if you find out, update (or extend, whatever is needed) the documentation page:
