Been trying to use the 'Custom Field' feature within an order (the std. woocommerce has always served my needs) . . . As you can see from the screenshot from an order - the custom fields are available to be selected & used? I have created one called 'repair-cost' using "Add Custom Field". My question is - do you just use the same field - say - 'repair-cost' on every order which you need to use it.. is this it ?? "Add New Custom Field" gives you an input text box - does this mean I'll have to buy a plugin to create other custom field types?
