It's sometimes useful to be able to hide the navigation or action buttons on a form so that the form appears more like a thank you page rather than a form. (How can I create a custom thank you page?)
To do this, under "Themes" >> "Custom" tab on the left menu, you can hide the top navigation buttons, and/or also the next > prev > submit buttons.
- Set "Navigation Position" setting to be "Hidden" (To hide the top navigation for "Single/Multi-Step" forms)
- Untick "Show Action Buttons" (To hide the Next > Prev > Submit action buttons)
