While at the TAE in Boston, I have tried to use the accordion widget "on the spot" to organize my conference notes. I have looked up the Accordion documentation and put the code together. It did not work. After a brief conversation with Richard Worth (thank you!) it turned out that I did not read well enough into the Accordion's assumptions on the DOM structure.
The documentation touches well on the "standard" cases of using lists, but it was unclear on how to use it with structure based on divs, or other elements. So I have put together a small blog entry about it at my page: http://blog.didenko.com/2008/10/accordion-experience.html
