p.s. I dont want to use isotope plugin just for that.
EDIT: looking the isotope code, they seems that they use translate css3 fuctionality but i cant simplify that part of their code.
@CrocoDillon thanks for the reply, I actually found the same solution my self last night but is incomplete because only the items on the same row are slide the rest just jump to the next position. I think as you said there is no easy way to do that, I found a plugin, [quicksand](http://razorjack.net/quicksand/ “”), which does exactly that and as I was looking on the code I realized that you have to convert the relative position of items to absolute and then moving them by keeping track of old and new positions.
p.s. I builded a nice live search for the iMDb, it looks nice but is not done yet. On the other post I will give a link later.
