Can all the windows in the Accordion be collapsed at once

Can all the windows in the Accordion be collapsed at once

I would like to use the Accordion version of jquery on a website to
save room and add value.
Is it possible to have all the windows in accordion mode collapsed at
once, its seems no matter what I do one of them is always open.
With them all collapsed , room is saved, and the headings look look
better, one on top of each other.
Cheers,
New to this forum so hope I posted in the right spot.
Thank you
