Multiple accordions, only want one open at a time

Multiple accordions, only want one open at a time

I have multiple accordions on a single page, I would like only one accordion open at a time, so if I have Accordion1 open, and I click Accordion2, I would like Accordion 1 to close.

It works this way if I click the accordions from the menu list at the top, but not if I click the individual accordion divs.

Sample here

Thanks for the help!
