Jquery + slideUp


I am using jquery slideUp to hide the box element. Normally the next element (box ) will take the position of the hidden element. But in my unbounce page the box hides but the next box will not replace the hidden one but stays in it’s original place.

Is it possible to have the next box go to the position of the hidden box?

this is my example page: http://unbouncepages.com/vier-vragen-0/
