A block resolver that replaces itself with a navigation list according to this instances configuration.
The resulting navigation tree can either be automatically generated from specified root nodes
of the input tree or by specifying entries manually (or a combination of both).
Serves as the implementation for the navigationTree directive, but can also be inserted into the AST manually.

excludeSections

itemStyles
the styles to apply to all navigation items in the list as a render hint
