Isotope is a very powerful jQuery plugin that allows you to create sortable, filterable (I’m sure that’s a word) masonry layouts (although you can have other layouts as well). Isotope is free for personal use (a commercial license costs $25, and an organizational license $90).
In this tutorial I will show how to add the Isotope code and scripts to a template. In my example, I will use the categories to filter a list of posts.
Update: I wrote a part 2 for this tutorial that shows how to use one category’s subcategories to filter posts.
