To collect certain data from the user I need to add several custóm fields to Billing info at checkout
(BTW: I would love, if I could add a new section as my collected data not really fits into the billing or delivery section)
I am wondering why user related data like name or email-address is not autofilled in the checkout form - and is there really no calendar field option?
To shorten my list of fields it would be great if I could display fields in 2 or 3 columns. I tried to find the related file to create an override, but couldn't find it. Can someone help?
