Features

✅ The category filter can be displayed as links or as a select dropdown field
✅ You can display a post count number near each category
✅ Custom All Categories text
✅ Works without page refresh (AJAX + Interactivity API)
✅ Sticky positioning
✅ Block styles customization (Font size, Padding, Margin)
✅ The block can add parameters to the page URL, for example, ?filter-category=travel

The plugin also has a PRO version, its main difference is that it supports filtering by any custom taxonomy – Tags, Product Categories, Product Tags, Brands, etc. It has a bunch of other features too.

Pro features

⚡️ Custom taxonomies are supported
⚡️ Multiple taxonomy filters within the same Query Loop block (for example, by categories AND tags)
⚡️ Sort categories (terms) in the filter alphabetically, by post count, or in a custom order
⚡️ The filter can be displayed as buttons with the possibility of style customization (Text color, Background color, Border, Border radius, etc.)

Tried the plugin and really enjoyed it. It doesn't overload the interface with shiny icons or notifications with suggestions to upgrade to a pro version. Plus, it works as it should.
