Thanks, I suggested you isotope few weaks ago for a tutoriel but finally I was not able to make it work correctly like you did. I finally use Views Quicksand to do the same thing. it was more easy to install.
Using Jquery Isotope to Display Content in Views, It’s Fancy.
Share with Others
Taking a content type and displaying it in a Drupal View is core to any Drupal website. If you are new to views, you can check out our Drupal views video. As you venture into views you will learn hundreds of ways to manipulate content to change the way the end user is able to interact with the content. To help enhance this, you can use the Views Isotope module. This module uses the jQuery isotope library to dynamically filter views content. As the title states, it’s pretty fancy.
To get an idea of what the library does visit the website for the library at http://isotope.metafizzy.co.
