Search and Filter items in grid layout with isotop javascript library

-
I want to create a portfolio page that listing all of my projects with search and filter functionalities. I search through a lot of javascript libraries and isotope is the only one that I can make it to work (I tried Filterizr, it worked, but if the number of items is about 100, everything will be broken):

Isotope official page: http://isotope.metafizzy.co/

This is a working example. It's easy, just read through the code and you will understand:
