Re: Live Code for APG: ARIA Accordion design pattern ready for review

Matt,

We have different types of accordions. Sometimes it is allowable to 
collapse all the panes, sometimes you can expand as many as you like, 
and sometimes there is one and only one expanded at any time. In this 
last case expanding one pane collapses all the others. We need to 
support all of these models.

Regards,

James
