Prevent shapes being re-arranged after fading out

Prevent shapes being re-arranged after fading out

Hi all,


I'm a real jQuery newbie. So I thought the best way to master jQuery is starting to code!

And as a matter of fact, I almost succeeded to write a shape-matching program. The aim of the program is to match filled shapes against contours of the shape at the bottom of the page. As soon as a shape matches its contours, it is faded out from the whole scene.   

The thing with this program is: as soon as the shape vanishes at the droppable object, all remaining shapes will move their position. But, I want them to stay in place.

The code is on jsFiddle.

Does anyone of you have a suggestion?


Thanks in advance!

Kind regards, Kees Epema
