Faceted filter UI
Build a filter set of facets — checkboxes, radios, a dropdown, a price slider, a search box, sort and a pager — and drop it beside any archive, like a shop sidebar.
Filter module
Real-time filtering for posts & WooCommerce.
Faceted, live filtering for any archive or listing — no page reload. Build a filter set with checkboxes, a price slider, search and sort, pull values from taxonomies, custom fields or WooCommerce, and place it with a shortcode, an Elementor widget, or a native Loop Grid. Results, per-option counts and active-filter chips update instantly.

Everything a filter needs
From a shop sidebar to a blog archive
One builder handles the WooCommerce shop filter and the simple category picker — with the facet types, data sources and live UX that usually take a premium add-on.
Seven facet types
Checkbox and radio, dropdown, price / number slider, live search, sort and pager. Mix them freely in a single filter set.
Any data source
Pull values from any taxonomy — categories, tags, Woo attributes (pa_*) — plus custom fields, post type, author and date buckets.
Live counts & chips
Per-option counts, active-filter chips and the result count update the instant a visitor clicks — every interaction runs over AJAX.
URL-synced selection
The current filters are mirrored into the URL, so a filtered view is shareable, bookmarkable and works with the browser back button.
WooCommerce ready
Filter by price range (variable products included), stock status, on-sale and rating, and sort by price, rating or popularity.
Its own value index
A purpose-built index keeps filtering fast and auto-reindexes incrementally when content changes — with a batched rebuild from the admin.
Elementor & Loop Grid
Four Elementor widgets — Filter, Listing, Result Count and Active Filters — plus a one-switch integration with the native Loop Grid.
Place it anywhere
Three ways to drop it in
Shortcodes, Elementor widgets or a native Loop Grid — the same filter set works through any of them, on any theme.
Shortcodes
Drop [wpstack_filter name="…"] for the UI and [wpstack_listing] for the results anywhere a shortcode works — page builder, template or widget area.
Elementor widgets
Four widgets — Filter, Listing, Result Count and Active Filters — for pixel-perfect placement inside Elementor.
Loop Grid integration
Already using an Elementor Loop Grid? Flip a single switch and it becomes your live, filtered listing — no extra widget.
How it works
Live in minutes
Build the filter set, index your content once, and place it — no external service and no premium licence.
01
Build a filter set
Add facets, pick each one’s type and data source, and set AND / OR matching and options.
02
Build the index
Run a reindex once. After that the value index keeps itself in sync as your content changes.
03
Place it on a page
Add the shortcodes, the Elementor widgets, or enable it on a Loop Grid — and filter live.
The builder
Build a filter, drag to arrange
Add a facet, pick its type and where it pulls values from, and reorder by dragging. Each facet carries its own options — AND / OR matching, a hierarchical category tree, ghost (0-count) options and “show N more”.
- Checkbox, radio, dropdown, slider, search, sort, pager
- Any taxonomy, custom field, post type, author or date
- AND / OR matching and a hierarchical tree
- Ghost options and a “show N more” link

Live UX
Instant results, shareable URLs
Every click refreshes the results grid, the per-option counts and the result count over AJAX — no reload. The selection shows as removable chips and is mirrored into the URL, so a filtered view can be shared or bookmarked.
- Results & counts update instantly over AJAX
- Per-option counts on every value
- Active-filter chips with a “clear all”
- Selection synced to the URL for the back button

Data sources
Filter by anything you store
A facet can read any taxonomy — categories, tags and WooCommerce attributes — or any custom field, plus post type, author and date buckets. Pair a custom-field facet with the Fields module and visitors filter your own data.
- Taxonomy — categories, tags, Woo attributes (pa_*)
- Custom fields — any post meta value
- Post type, author and year / month date buckets
- WooCommerce — price, stock, on-sale and rating

Filter products by a price range that includes variable products, by stock status, by what’s on sale, and by rating — then sort by price, rating or popularity. Results render through your theme’s own product cards.

FAQ
Filter, answered
No. Every interaction runs over AJAX against a built value index — the results grid, per-option counts, active-filter chips and the result count all refresh in place, and the selection is written to the URL.
Seven: checkbox and radio, a dropdown, a price / number slider, a live search box, a sort control and a pager. Add an active-filters chip strip too. Mix them freely in one filter set.
Any taxonomy (categories, tags, WooCommerce attributes pa_*), any custom field (meta), post type, author, date buckets (year / month), and WooCommerce price, stock, on-sale and rating.
No. Filter works on any posts or listings using taxonomies, custom fields, post type, author and date. WooCommerce is only needed for the price, stock, on-sale and rating facets — and its results render through your theme’s product cards.
Three ways: the [wpstack_filter] and [wpstack_listing] shortcodes; four Elementor widgets (Filter, Listing, Result Count, Active Filters); or by flipping the WPStack Filter switch on an Elementor Loop Grid.
Yes. Each option shows a live count of how many items it would return, the current selection appears as removable chips with a “clear all”, and the whole state is mirrored into the URL for shareable, back-button-friendly views.
Filter keeps its own value index so filtering stays fast without heavy queries. It reindexes incrementally when content changes, and you can run a batched full rebuild from the admin after bulk changes.
Filtered URLs get a canonical tag back to the base archive, with an optional noindex on filtered pages. A full accessibility pass adds keyboard operation, ARIA and managed focus.
Both. Choose Instant to refresh results the moment a facet changes, or the “Apply filters” button mode to batch several choices and apply them at once — handy on large catalogues.
Yes — like every WPStack module, Filter is included in every plan. Switch it on per project from the modules panel whenever you need it.
