The Save button lets a website visitor save the progress of their form and come back later to complete it.
To use Save for forms in WordPress, the Save to Submissions action must be active on the form with the Save event enabled. Actions that run when the Save button is clicked are configured in the Actions sidebar.
The Save button also includes field settings for label, help text, ARIA label, styles, visibility, disabled state, user status, custom classes, custom attributes, and breakpoint-based layout control.
