This Accordion view was copied from the demo at
( Their copy of prototype.js seems not to be released elsewhere. )
I also slavishly copied the stylesheets from the demo page; they definitely
enhance the overall effect. I try to use panelHeight:'auto', but I use
firefox and don't see any effect.
There was one problem: before rico.js version 1.1.2, the text could overflow the open accordion box, causing unpleasant effects. I'm hoping that's fixed now. As I type, I haven't yet proven that it works properly !
