To separate between fields with large titles, open a Field setting, then go to Section Header. Here's a video that explains how to add section headers to your form.
This feature allows you to organize your form content in a more user-friendly way. When this option is enabled, users can click on section headers to collapse or expand the corresponding section content.
The collapse/expand feature is automatically ignored if the "Enable multi-page form for section headers" option is activated. The user will navigate through the form by moving from page to page rather than collapsing and expanding sections.
