Payment Form Layout In Single Column

I noticed that instructions for adjusting the Payment Form for a single column layout is not available yet. In the meantime, how would I go about creating a form that is not split into two (2) columns?

I have the "Form Layout" field empty which should force the form to display as a single column. Hmmmmm.

Thank you.

Okay, self help on this one. If you enter "Default" in the Form Layout field, then the form will display in a single column.

DO NOT leave blank as instructed.

Best,
