Making required fields - optinal

-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4.1

In which file can I make address and shipping fields optional "not-required" in back-end?
I only use hikashop for managing customers and orders via phone or online, COD payment only.

Hi,

I suppose that you want to edit the file administrator/components/com_hikashop/classes/field.php and add a line like this: before the line:

Thank you, I did that but it only removes the star *, nothing more.

I was using mijoshop 3 form the day they've relesed it. Since then I searched in "all" core files, edited hundereds of lines to meke the default reqiered fields optional. I succeded in some pages but in most of them I couldn't.
That's why I thought in hikashop core files should be edited.
By "custom fields" I can do what ever I want with all default address fields easily. :woohoo:
There is one thing, If one of the required fields in billing or shipping address lift empty it closes the fields like every thing is OK, but doesn't save or notify. I undid the changes in feild.php files
