WooCommerce: Display Custom Filters @ WP Dashboard > Products

If you go to WordPress Dashboard > Products you will find default product admin filters such as “Select a category”, “Filter by product type”, “Filter by stock status”. What if you want to add more custom filters to let your shop managers find products easily?

For example, you could add “Filter by product tag” (“product tags” are one of the two default WooCommerce “taxonomies” together with “product categories”). Or, if you use custom taxonomies such as product brands, you could add a “Filter by product brand” dropdown.

Thankfully this is super easy – and here comes the proof 🙂
