Accordian collapse all when page loads

Accordian collapse all when page loads

I have found the nice feature of being able to collapse all the accordian divs when you click on the currently open div. Is it possible to default the accordian to have all divs closed when the page loads? I am very new to jQuery so any help would be appreciated. If you need any more information or code please just ask but the code I am using is the exact same as the example on the jQueryUI page.
Cheers
