Forms are not negotiable when it comes to your funnels. Funnels are meant to be used as landing pages that you have your ads direct to so you can collect information from leads! The forms are what allows you to collect the information.

Forms start in the Form Builder, where you can customize the questions in each form and the color of the buttons.

After you have it customized, you can use the form element in your funnel and select the funnel that you customized to place it onto your page!
