What feature allows admins to create layouts that optimize limited space by using expandable and collapsible sections?

The feature that enables administrators to create layouts that optimize limited space through the use of expandable and collapsible sections is collapsible layout categories. This functionality allows sections of content to be hidden or displayed as needed, thereby improving the organization and user experience on a page by minimizing clutter. When sections can expand and collapse, users can focus on the information they need while keeping the interface clean and navigable.

It's particularly beneficial in environments with limited space, where displaying all information at once could overwhelm users or create a convoluted layout. By utilizing collapsible layout categories, admins can streamline how information is presented, making it more user-friendly and efficient.
