Order Custom Field

Hai,
I just purchased Essential Hika Shop because I need to have the "Order Custom Field" where customer can input their personalized name in the product page before the add to cart button.

But in Display->Custom fields, in the table, I only find "Address, User, Product and Category". I can't find "Order" or "Item" in the Table.

Can you guide me?

Thanks much..

That's normal. These custom fields are only in the Business edition:

Custom fields for orders, items and entries as well as custom file type
