Section

Collapsible groups hide fields until you open them. When a page is loaded, these groups are closed by default, which is useful for hiding a large number of fields. When the section is closed, the page will shrink. If there are hidden field errors upon hitting save, an error message will appear near the section name.

An optional feature is auto-collapse: when you open one section, any other open section closes automatically. This reduces scrolling and helps keep large forms easier to navigate. You can apply this feature to all sections on a page, or set up groupings so only sections within the same group auto-collapse.
