Admin Taxonomy Filter helps you to filter posts or custom post types in the admin area (the post list table) by custom taxonomies. It’s similar to filter posts by categories, which is supported by default.
The plugin supports filter by multiple taxonomies and has settings to let you choose which taxonomies are filterable.
The plugin is open source and hosted on Github. If you have any problem or feedback, please open an issue.
