i think you didn't understand my question
I know that i can move the hook item_detail inside the file item.php and reposition it BUT it moves allthe details and not only the custom field i want to move !
I want all other custom fields to stay where they are, AND ONLY one specific field to move on other position
See what i mean ?
I think that there must be some piece of code that allow us to unset a specific custom field based on its unique name we set at the backend.
