Working with Listings
Each listing is regular WooCommerce product with the product type “Listing”. You can create new listing in the exactly same way how you create products but it is required to set product type to “Listing”.
When you set the product type to “Listing” new tabs will appear. From this point you will to edit listing information like contact, GPS position and so on. If you are looking for adding new fields you can use WooCommerce actions and filters or use third party plugin like ACF.
