Slidetoggle Box one at a time

Question

I'm using this piece of code on jsfiddle ( http://jsfiddle.net/ErickPetru/65wSn/1/) which was posted in a previous question by me here: Slidetoggle with a close button - jQuery

My question is how can i adjust the jquery so that only one box is shown at one time?
