Creating 3rd level nav for your content

IMPORTANT: 3rd level navigations will only appear in the left-navigation.

To create a 3rd level navigation, create a new page and add the parameter second_nav_title in the main header of the page.

The second_nav_title corresponds to the 2nd level navigation and the title will be the title of the page.

In the example below, “Github Repository” tells isomer that this page belongs to the Github Repository second-level navigation while the page title is “Overview”.

---
layout: leftnav-page-content
title: Overview
permalink: /github-repository/overview/
breadcrumb: Github Repository - Overview
collection_name: Fill in collection of the nav bar. You may get this from other pages in the navbar folder
second_nav_title: "Github Repository"
---

The file will following the naming convention of [number][alphabet]-[filename].md. For example:

• 1a-who-we-are.md
• 1b-organisation-structure.md
• 1c-contact-us.md

The number will group the navigation together while the alphabet will determine the order of the pages.
