How are the Craft docs created? The Craft documentation on Section Types state that they themselves are created using a Structure. Can someone explain the method they used here?

What I'd really like to see is the Twig code for the left hand navigation. Are there multiple Structures here (to account for the headings) and if not, how are the headings set?

Thanks!
There is a Documentation structured section with three entry types.


Heading Only
Page
Link


The Getting Started, Core Concepts, etc. headers are the Heading Only entry type. The only field is has is a title.

The majority of the docs are using the Page entry type.

The Link entry type is used for the entries like Full Templating Reference and Plugin Development that open into a new window, and those are their own separate structured sections.
