WPEnhanced Ajax Filter Blocks

Free by design. Powerful by default.

WPEnhanced Ajax Filter Blocks is an AJAX filter plugin for the WordPress block editor. Build filterable blogs, shops, directories, and listing pages where results update instantly – without a full page reload.

Most filter plugins lock the useful bits behind Pro. This one is built the other way around: the free version is intended to be the full product for most websites. Design controls, multiple filter types, AJAX results, custom fields, WooCommerce support, and custom post types are all included – no essential features paywalled.

Whether you run a WooCommerce store, a content-heavy blog, or a custom post type directory, you can create a modern faceted filtering experience using only blocks. No shortcode soup. No theme lock-in.

Why site owners love it

• Free by design – Built so most websites never need to upgrade
• Full design controls – Style filters and loops in the editor without paywalls
• Instant AJAX filtering – Results update without a full page reload
• Built for Gutenberg – Native blocks for filters and archive loops
• Works beyond blogs – Posts, WooCommerce products, and any public custom post type
• Flexible filter types – Checkboxes, dropdowns, radios, ranges, search, and more
• Custom field ready – Filter by custom field values using their meta key
• Shop-ready – Categories, tags, attributes, price-style ranges, and more
• Shareable filtered URLs – Visitors can bookmark or share filtered views

The three blocks

1. Archive Loop – Display posts, products, or custom post types in a grid or masonry layout with standard pagination
2. Filter Posts – The filter panel visitors interact with (sidebar or top-bar layout)
3. Filter Posts Item – Each individual filter control inside Filter Posts (taxonomy, search, custom field, attribute, range, and similar)

Put them together and you get a complete filterable archive – built in the editor, running live on the front end.

Perfect for

• WooCommerce product catalogs and shop filters
• Blog archives filtered by category, tag, or keyword
• Directories and membership listing sites
• Portfolios filtered by project type or skill
• Real estate or inventory listings with custom fields and taxonomies
• Resource libraries and knowledge bases with faceted browsing

How filtering works

Filtering uses the WordPress REST API. When a visitor changes a filter, only the loop results refresh – keeping the rest of the page in place. Optional URL parameters keep filtered views shareable and bookmarkable.

4. Choose what to filter by (categories, tags, taxonomies, custom fields, product attributes, and more)
