What It Does
WP Categories Widget is a sidebar widget that displays a list of categories for any registered WordPress taxonomy, including the built-in category system, WooCommerce product categories, and custom taxonomies for CPTs such as projects or listings. It lets you pick which taxonomy to show and place the output in any widget-ready area without writing code. It is essentially a more flexible replacement for the default Categories widget that ships with WordPress core.
Who It's For
This plugin is a fit for site owners running WooCommerce stores, directories, portfolios, or any site that relies on multiple custom taxonomies and wants a lightweight way to expose those category lists in widget areas. It is also useful for bloggers who want a simple, no-frills category list without the overhead of a full menu plugin. Developers building small-to-mid sized sites with one or two taxonomies will get the most value.
Who Should Skip It
If you already use the built-in WordPress Categories widget and only need standard post categories, there is no real reason to install this. Users who need accordion menus, mega menus, or post listings inside categories should look at a more feature-rich alternative.
The Bottom Line
WP Categories Widget does one thing, taxonomy-aware category lists, and it does it cleanly with current WordPress and PHP requirements. The main caveat is the complete absence of public support activity, so you are betting on a maintainer who has not yet been tested under fire. For simple taxonomy display needs it is a solid, lightweight pick, but anyone wanting menus, accordions, or post thumbnails should look elsewhere.
