Hello boys and girls
In the ever-loving spirit of OSS, here's another feature for s.a.u.
In particular it's called Effect.Accordion, and is a scriptaculified
version of openrico's Accordion.
Work in progress, I'll submit further modifications as the come in, but
this is 90% of what needs to be done. I anticipate some bugs when I
start using it more.
Tested on FF1.5 and IE6/7.
Comments are welcome, and in fact solicited. I'd appreciate all bugfixes
sent either to this list or myself.
Yours,
-Rob
PS. This isn't a patch, it's just JS. However this server won't allow
attachments with a .js extension, which is, well, ridiculous.
