When you select an element in the structure, it will be highlighted on
the workspace. Its settings will be shown in the Element
settings area and can be changed there.
Layout elements can be moved via drag & drop in the layout tree
if their arrangement needs to be changed.
Clicking on Control elements switches to a view in which you can load, and then edit, the settings for
General HTML properties (such as body, table, or div), Advanced properties
(such as login, warnings, error messages), and Controls (such as edit fields or buttons) in the Element settings area.
