The Admin Custom Order Fields extension allows you to add fields to an order for details, notes, dates, and more. These fields can also be used to sort or filter orders in the order dashboard, and are geared towards streamlining and centralizing order information and notes.
By default, these fields can only be viewed by the administrator, but can optionally be included on the customer?s ?My Order? page. To learn how to optionally include this information, check out the section on Field Attributes.
