You can access the "Extra fields" page by clicking the left side "Extra fields" link under "Products".

Or you can click the "Extra fields" icon on the main page of your personal administration area.

To add an extra field:

Enter the field name into the "Field name" field. Note: It is recommended to have no duplicating "Field names" in order to avoid confusing customers. If you wish to have a default value automatically populate the extra field on the "Add new product" and "Modify product" page, enter the value into the "Default value" field.

It is important to note that the "extra field" that you add will be displayed on all of your products and not just a select few.

To add the extra field to your products table, press the "Apply" button. Once applied, the new field is available on the "Add new product" page and "Modify product" page and is displayed to the customer on your product pages.

If you want to remove an extra field, click the "Delete" button next to the extra field that you want to delete.
