This guide shows you how you can create a custom Select field type in the product editor of WooCommerce. A select field (or drop-down list) is useful when you want to allow only one option from a predefined selection of options. Tax Status is an example existing field which uses the select field type for products. This guide also shows you how you can output the value selected and saved from the product editor on the front-end.
