Add Shipping Adress Same As Billing Adress At Checkout


So in the admin of the site when i open a customer i see i have the option to check if his adress is the same as billing adress so the function exists in the database.

all i wanna know is How can i add a checkbox like that to the checkout page ?

Just make sure the two sections have the same setup and fields.

Go to Administration -> Profile fields and compare Checkout columns in the Billing address and Shipping address sections. They should be equal

Thanks ! it worked.
