## Description
MRZ Product Filter is a minimalist product filter for WooCommerce. It builds a filter
panel from your product categories, attributes and tags, plus a price slider, and
lets shoppers narrow down the shop or category archives with instant AJAX updates.
A chosen “color” attribute is rendered as color swatches.
Each filter set is configured from a dedicated Custom Post Type and can be displayed
automatically on the shop / archives, or placed manually with a shortcode. The markup
is intentionally minimal (wireframe, black & white) so you can style it to match
your theme.
#### Features
* Filter by product categories, tags, brands and product attributes (checkboxes,
radio buttons or dropdowns).
* Price range slider (min / max).
* Color swatches for a chosen attribute — the color is stored on each attribute
term and reusable.
* AJAX refresh of the product loop, with native URL parameters (shareable, SEO-
friendly) and a no-JavaScript fallback that filters through WooCommerce natively.
* Collapsible sections (native ``), with a per-section and global “expanded
by default” setting.
* Automatic display on the shop and category / tag archives (left column or above
the products), or manual placement with `[mrzpfe_product_filter id="X"]`.
* Multiple filter sets via a dedicated Custom Post Type — a different configuration
per context.
* Translation-ready (text-domain `mrz-product-filter-exp`, .pot file provided).
#### Requirements
* WordPress 6.3 or later, PHP 7.4 or later.
* WooCommerce.
#### Privacy / external calls
MRZ Product Filter makes no external HTTP calls, loads no remote resources, and
collects no telemetry. Everything runs locally on your site.

## Changelog
#### 1.4.1
* Maintenance: build/CI update only (deploy workflow). No functional change to
the plugin.
#### 1.4.0
* All internal code identifiers now use the `mrzpfe` / `MRZPFE` / `Mrzpfe` prefix(
4+ characters) per the WordPress.org guidelines: functions, classes, namespace,
constants, options/transients, shortcode (`[mrzpfe_product_filter]`), AJAX action
and the custom post type (now `mrzpfe_filter`). Note: an existing filter set
created with a previous version must be recreated.
#### 1.3.1
* Renamed the plugin to “MRZ Product Filter Exp” so the WordPress.org slug matches
the text domain (`mrz-product-filter-exp`). Set the `Contributors` line to the
owning wordpress.org account. Cosmetic / metadata only.
#### 1.3.0
* New: contextual filters — on a category / brand / tag / attribute archive, every
filter (categories, brands, materials, attributes…) only lists the terms actually
present among that context’s products, with the real per-context counts. Avoids
offering a choice that would return no products.
#### 1.2.0
* New: WooCommerce brands (the native `product_brand` taxonomy) can be added as
a filter source, like categories and tags. Shown only when the taxonomy exists.
* New: optional “sticky” left column — the filter panel follows the scroll, with
a configurable top offset (desktop / tablet).
#### 1.1.1
* Fix: the “products per page” override is now forced via pre_get_posts, so it
applies even when the theme sets its own products-per-page (e.g. Salient).
* New: extra “large screen” column level (≥ 1600px) in the responsive columns option.
#### 1.1.0
* New: option to control the number of products per page and the number of columns
per row, with responsive breakpoints (desktop / tablet / mobile). Applies on
the shop and archives targeted by the filter set.
#### 1.0.0
* First release.
* Filter by categories, tags, attributes and price, with color swatches for a chosen
attribute.
* AJAX product loop refresh with native URL parameters and a no-JS fallback.
* Automatic display (left column / above products) or shortcode placement, configured
from a Custom Post Type.
