This document discusses using the Isotope JavaScript library to filter a large list of custom post types in WordPress. It explains that Isotope allows creating filterable and sortable layouts without a plugin, and provides instructions on enqueueing, registering, and using Isotope with WordPress by creating filter buttons, querying posts, and outputting items with a selector for layout. A demo is linked and contact information for the author is included.
