Is it possible to customize the checkout page in Bitrix?

Question

1C-Bitrix

Can I create a custom checkout form? I know that it is possible to strictly register the fields through the API, but this is not flexible, and if some module for registration is installed, then it will not work ... And the standard form cannot be changed.
For example, how can such a form be made? prntscr.com/ecki0b

Answer 1

Open the template and go. The fields are all standard.
