Sections
The default component used to render an object is a section.
The title of the section can be derived from the title attribute of the object or from layout.title. An empty or null title will make the section into a simple container for its children.
The attribute layout.option.titleDepth can be used to configure the title tag (h1, h2, etc). Its default value is 2 and it is incremented automatically when nesting sections.
