The ultimate
filtering framework.
Every feature is production-ready, extensible, and engineered for high-performance sub-200ms load times. Zero bloat, infinite scale.
01 — Core Facets
12 facet types.
Every pattern covered.
Map any facet to any data source: taxonomies, post meta, ACF fields, or Woo attributes. Every UI configuration is built right into the admin panel.
Checkbox
Multi-select with counts. OR logic between values.
Radio
Single-select exclusive — click another to switch.
Dropdown
Space-efficient select control, single or multi.
Range Slider
Dual-handle numeric range with prefix/suffix.
Date Range
From/to date pickers for any date meta field.
Search
Live text input with debounce and min-chars.
Autocomplete
Suggestions dropdown from the live index.
Color Swatch
Hex-mapped color circles or squares.
Star Rating
1–5 star minimum filter, WooCommerce-ready.
Toggle
Single on/off switch for binary filters.
Hierarchy
Expandable tree for nested category terms.
Button Group
Pill buttons, single or multi-select.
02 — Layout & Output
Visual drag-and-drop Grids.
Build completely custom cards using the visual 12-block Card Builder, then inject them into 5 different responsive grid layouts.
5 Layout Configurations
Grid
Responsive CSS grid with configurable columns per breakpoint.
Masonry
Waterfall layout via CSS column-count — perfect for varying heights.
List
Full-width single column — ideal for articles & search results.
Carousel
Horizontal scrolling with nav arrows and optional autoplay.
Table
Tabular layout rendering custom blocks as organized row columns.
Dynamic Template Tags
Inject live post data using double braced {{tag}} templates.
{{post.title}} // Native post title
{{post.permalink}} // Resolves to URL
{{meta.PRICE}} // Custom meta injection
{{acf.field_name}} // Auto-resolves ACF
/* WooCommerce Specific */
{{wc.price}} // Formatted price HTML
{{wc.rating}} // Average star rating
{{wc.sku}} // Product SKU string
03 — Intelligent Indexing
Sub-200ms on 50k posts.
FilterX maintains a high-speed, vertical filterx_index table. AJAX requests never scan raw metadata tables, locking latency incredibly low across huge datasets.

04 — API First
Developer First.
Always.
FilterX is not a black box. Exposed via 31 REST API endpoints and over 100+ native PHP hooks, giving full override capabilities to your engineering team.
PHP Service Container
Overrides via PSR-11 dependency injection rather than messy monkey patching.
Native JS Events
Globally scoped window.FilterX actions for 100% frontend UI control and overrides.
// 1. Programmatic Filter API
FilterX.setFilter('products', 'price', [10, 500]);
// 2. Dynamic PHP Query Rewriting
add_filter('filterx/grid/args', function($args) {
$args['orderby'] = 'meta_value_num';
return $args;
});
// 3. Extensible DOM Listeners
document.addEventListener('filterx:results', (e) => {
const { total } = e.detail;
console.log(`Found ${total} matches`);
});
