The Navigation Flow setting allows you to determine if your Standard & Campaign Donation Forms use a one or two page process.
This setting is configured here: Web Content > Form Links & Landing Pages.
Click [Change] under the Navigation Flow column to view your options.
The one-page option will combine the contact information and payment processes into a single page.
This is the default navigation flow for your donation form. This will split the donation process into two pages. The first page will collect contact information and end with a Submit button.
The second page will collect payment information.
