Using the Dividers element
The Divider element is a thin horizontal line that can be used to break up sections within a form, or separate specific widgets from the rest of the form. Dividers DO NOT capture any data and will not show up in the Data Feeds.
Select Divider under Element Properties on the left side of the page. You will see a new element pop up on your device view.
Because this element does not capture any data, it is not necessary to fill out the Label or Description fields.
Click the save icon at the top right corner of the page.
