The basic structure of a page is created by placing various template elements on the page using drag & drop.
A completely empty page initially contains only the red-colored Base Container.
Layout areas can be dragged and dropped into this base
A layout area creates one or more orange-colored containers in which layout rows can be placed.
Layout rows create blue-colored containers in which content elements can be placed.
The content elements ultimately represent the actual content of the page, e.g., through content sections, lists, media, etc.
In principle, any number of suitable elements can be inserted into each container. For example, several layout rows can be inserted one below the other in a layout area to create a complex page layout.
Layout groups have a special status. They generate predefined layouts for specific areas of application, such as the header or footer of a page. The container in which a layout group can be used depends on the group itself. For example, groups for headers or footers can be stored directly in the base container as layout areas.
