Isotope is an exquisite jQuery plugin for magical layouts. You can reveal & hide items with filtering and re–order items with sorting. The syntax is very simple, but the layouts can be really dynamic and intelligent. And also, there is progressively enhanced for CSS3 transforms and transitions.

However, please note that it is free for non-commercial use only. Commercial use requires purchase of one-time license fee per developer seat. You can always look at Masonry for alternatives.
