When Auto-Scroll on mobile is enabled, the form jumps, or automatically scrolls ahead to fields a supporter needs to fill to submit, saving them the trouble of sifting through content before arriving at the actionable part of the form. This feature increases conversions by supporters on mobile devices by directing them to the first set of form fields.
Step 1: Navigate to Online Actions and Select the Form Type
Each type of Online Actions form follows the same workflow. The forms available to you depend on the packages your organization purchased.
To create your form, open Online Actions from the sidebar and select Create New Form and the type of form to create.
Step 2: Navigate to the Basics page
While on your form, scroll to the section titled "Auto-Scroll on Mobile" and select the checkbox. 
While the auto-scroll option is off by default for embedded forms, you can change this by setting the data-mobile-autofocus option to true in your embed code. To do so, navigate to the "Link & Embed" button at the top right of your screen. 
Step 3: Publish Your Form
On the Confirmation page, scroll to the bottom of the page and select "Publish Changes".
