Fill out any custom fields you have created.
If you are creating a product type different than the General product type and you have added any custom fields to the product type, they appear when you are creating a product of the selected type.
For more information about custom fields, see Adding custom fields to content items.
To display a custom field in the public side of your website, you must add the field to the widget template which you use to display the product. For more information, see Creating and editing widget templates.
EXAMPLE: You have created a product type Book and you have added a custom field Author. When creating a new product of type Book, the Author field will appear. Then you must change the template that the Products list widget is using, so that it displays the Author field to a website visitor, who is viewing the book you have created.
