Custom Post Types power directories, real estate websites, portfolios, event listings, and business platforms. As your content scales, users need a smarter, faster way to find what they’re looking for — without the frustration of full page reloads.
Why Use AJAX Filters for Custom Post Types?
Default WordPress archives are often limited when websites contain hundreds of posts or listings. AJAX filters allow visitors to quickly narrow down content using categories, tags, custom taxonomies, or search terms — without refreshing the page.

How to Create AJAX Filters in WordPress
The setup process is straightforward and requires no custom coding. Follow these steps to get your filters running:

Install Category AJAX Filter
Download and activate the plugin from the WordPress plugin repository. Navigate to the plugin settings panel in your dashboard.
Select Post Type & Taxonomies to Filter
Choose which CPT to target and which taxonomy terms should appear as filter options in your UI.
