Changing portfolio display and animation

Ok, so I posted something in another section (Themes and Templates) but figured that it would suit better in here, so i’m just gonne link to the other thread and give a small recap;

http://wordpress.org/support/topic/changing-portfolio-display-and-animation?replies=7

What happens: You can click on either ‘Architectuur’, ‘Meubel’ or ‘Objecten’. And the items that are relevant are moved to the first, second, third, … place and the items that don’t matter fade out.

What should happen: All the items should stay in place and the items that are irrelevant should fade out and the relevant items mustn’t change place, like so; http://themewich.com/aware/
As you can see they don’t move, they all stay in place and some of them just fade out.

Some info that might be useful:
– the ‘animating’ aka moving of the images/projects is done by jquery and isotope
– the piece of code that i’ve been messing with is;
hiddenStyle:{opacity:0,scale:.001},visibleStyle:{opacity:1,scale:1},containerStyle:{position:”relative”,overflow:”hidden”},animationEngine:”best-available”,animationOptions:{queue:!1,duration:800}

Getting sort of desperate. I’ve posted this on some other forums and none of them gave me a decent answer…. Giving a link to a person or a freelancer of whatever that might know this is appreciated as well, thnx!

ps: if there are any mods reading this, really sorry for the double thread, you can delete the topic in the Themes and templates section.

Regards!
