I am using the Spry Accordion How can I make it so that all panels appear as a default of closed?

I have gone through the documentation and am unable to find a way to set the default value of the panels to closed. I have looked at the java script file of the spry and have changed some null values to true and some to but this has no effect. I have seen this spry used in other sites and the panels are closed at the on set when the page is called. I would like any help  you could give me thank you.
