The Navigation Presentation is intended to help the user move around the content.

The Navigation Presentation will vary depending on the context where the Navigation is shown. For example:

Site Header shows Navigation Links as a horizontal list, and children Navigation Links are within dropdowns that appear on hover.
The Sidebar shows a vertical list of Navigation Links, and children links are indented beneath

Navigation Links

A hierarchy of links

Navigation Block Types

Critically, many blocks will not be shown in the Navigation Presentation. The following blocks will appear:

Heading: Shown as navigation links, clicking will go to the Document with the Heading Block Node highlighted, or a focus view of the Block Node
Feature: Same as Heading blocks
Embeds
Query: Each result of the query is shown as a navigation link

When the Navigation Content includes an Embed Block, the view attibute is critical to define the Navigation Presentation.
