⭐ Key Features CAF includes the core features you need to create professional, fully customized post or woocommerce product filters. From instant AJAX filtering to pre-built templates, everything is designed for simplicity and power.

AJAX-Powered Instant Filtering: Filters use AJAX to update results instantly without page reload. Visitors see filtered posts and products in real-time as they select categories, tags or search anything across your content.

Drag & Drop 3-Step Builder: The visual CAF Builder simplifies filter creation into three steps: Query & Filters to set filtering logic, Post Item Template to design post and product cards, Layout Settings to control columns, posts per page, gaps, sort order, filter position and pagination.

Works with Any Post Type: Blog posts, any custom post type and WooCommerce products – one filter for all your content.

Pre-Built Template Library: Start with ready-made filter layouts and post item designs. Export your work as JSON to reuse across sites or import templates from other filters you’ve built.

👑 Category AJAX Filter Pro Take your filters to the next level with Category AJAX Filter Pro plugin. It adds advanced filtering, deeper customization and extra integrations. From AI-powered search to WooCommerce swatches and smart badges, Pro gives you the tools to build filtering experiences that match your exact vision.

AI Search: A visitor types “red shoes under 50” and gets the right products. AI Search understands what people mean, matching intent against your content, taxonomy terms, brands, attributes and price – not just exact keywords. Works on posts, custom post types and WooCommerce products. See the live AI Search demo.

Custom Fields in Filters: Extend filtering beyond taxonomies by letting visitors filter with custom fields, including all WooCommerce product custom fields, using Checkbox, Dropdown, Range Slider or Search modules, with the ability to target the search box to specific custom fields for more focused searching.

Sort Filter Terms: Manually reorder categories, taxonomies, brands, attributes or custom field terms in Checkbox and Dropdown filters using drag & drop, instead of relying on alphabetical or count-based ordering.

Icons & Images on Filters: Add an icon or image to any filter term alongside the label or in place of it. Use brand logos, colour swatches or category icons on checkbox and dropdown filters and on custom field terms.

Voice Search: Let visitors search hands-free using voice input, with a customizable microphone icon you can position left or right and control the listening state feedback they see while speaking, making filtering more accessible and convenient.

SEO Controls: Keep filtered pages crawlable and indexable with Filter With URL support and schema markup, so search engines understand your filtered content.

Advanced Layout Controls: Place advanced pagination options like Load More, sorting dropdowns, selected filters and result counts exactly where you want them across four flexible positions: above filters, below filters, above the post grid or below the post grid, with drag & drop control that lets you arrange them however you need, even stacking multiple modules in the same position.

Analytics: Get detailed insights into how visitors use your filters, including total filter clicks across categories, attributes, brands and selected price ranges, which filter combinations return zero results, clicks broken down by device type and a complete list of search keywords visitors used, all viewable across custom time periods to identify trends and gaps in your content and store.

Prefix and Suffix Options: In listing add custom text or icons before and after data throughout your layout in key modules like Post Title, Custom Field, Post Button, Product Price, Add to Cart and Badges, as well as result counts in your layout controls, so every piece of information displays exactly how you want it with complete customization over presentation.

Float Button: Take full control of how your filter appears on every device. Keep it inline or in a sidebar on desktop and show the same filter as a floating button on mobile and tablet, with full customization of the button text, icon, panel animation direction and overlay color.

Product Attribute Swatches: In listing show product attributes as selectable text, color or image swatches directly on product cards, each fully styleable. Shoppers pick their size or color and add the exact variation to cart without opening the product page, turning your filtered grid into a fast, one-stop shopping experience.

Smart Product Badges: In listing go beyond the standard Sale badge with New, Best Seller, stock status, stock quantity and discount badges. Each badge comes with its own conditional logic, set a Low Stock Threshold to trigger a badge when inventory runs low, show discounts as an exact value or a percentage off and combine these options to build flexible badges that appear exactly when they should.

More Pro features:

Dynamic Term Counts, Extended revision history, Custom fonts upload, Global font settings, include/exclude posts/products, Icon library, Icons/images for terms & custom fields, Masonry layout, Loader styles, Elementor Loop Builder support, Quick backend navigation.
