Table of Contents

A table of contents (TOC) defines the structure of a set of documents.

YAML TOC

To add a TOC, create a file named toc.yml. Here's the structure for a simple YAML TOC:

items:
- name: Tutorial
  items:
  - name: Introduction
    href: tutorial.md
  - name: Step 1
    href: step-1.md
  - name: Step 2
    href: step-2.md
  - name: Step 3
    href: step-3.md

The YAML document is a tree of TOC nodes, each of which has these properties:

  • name: The display name for the TOC node.
  • href: The path the TOC node leads to. Optional because a node can exist just to parent other nodes.
  • items: If a node has children, they're listed in the items array.

The toc.yml file in the docfx.json folder will be used to fill the content of the navigation bar at the top of the page.

Nested TOCs

To nest a TOC within another TOC, set the href property to point to the toc.yml file that you want to nest. You can also use this structure as a way to reuse a TOC structure in one or more TOC files.

Consider the following two toc.yml files:

toc.yml:

items:
- name: Overview
  href: overview.md
- name: Reference
  href: api/toc.yml

api/toc.yml:

items:
- name: System.String
  href: system.string.yml
- name: System.Float
  href: system.float.yml

This structure renders as follows:

Overview
Reference
├─ System.String
├─ System.Float
