Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site. Why active installs don’t tell the whole story →
WP PlugIndex currently records Multiple Category Selection Widget version 4.0.0 as active, updated 8mo ago and tested up to WordPress 6.9.
Overview
About this plugin
Turn your WordPress post categories into a search powerhouse! This plugin gives you a set of dropdown menus based on parent categories and their sub-categories. Users select one sub-category per parent, and the plugin filters posts matching the selected combination.
Available as:
Gutenberg Block — “Multi-Category Filter” in the block inserter (new in v4)
Classic Widget — “Multi-Category Selection” in Appearance > Widgets
Shortcode — [mcsw] on any page or post
Features:
AND / OR category filtering — find posts matching ALL or ANY selected categories
AJAX chained drilldown — selecting a parent dynamically loads its children
Display form above results on category pages (optional)
Sample use case:
Real estate — set up parent categories like “Bedrooms”, “Bathrooms”, “Price Range” with sub-categories beneath them. Users filter listings by selecting from each dropdown.
x:
PHP sessions have been removed entirely — the URL now carries all state, which means better compatibility with caching plugins, load balancers, and modern hosting
jQuery has been replaced with vanilla JavaScript
CSS classes have changed from wpmcsw / wpmm to BEM-style mcsw-* classes — update any custom CSS
The old select-chain.js in the plugin root has been replaced by js/select-chain.js
