Navigation block

The vf-navigation component is a horizontal list of links to key pages of the website.

github location npm version

Usage

Global navigation variant

This variant of the vf-navigation is to be used as part of the vf-global-header to give a few 'quick links' that will be on every page.

Main navigation variant

This variant of the vf-navigation can be used to link to sections of the site, or part of the site the parent section.

This is typically placed below the vf-hero component but can be also found below the vf-global-header.

There should be only one use of vf-navigation--main on a page.

On this page navigation variant

The vfNavigationOnThisPage JavaScript adds a quality-of-life improvement by automatically activating sections as the user scrolls them into view on the page. This sticky element allows users to quickly jump between sections on longer pages.

  • There should be only one use of vf-navigation--on-this-page on a page.
  • Anchor targets need an element id: id="container-1". This can be added to any item on the page, but would most logically be added to a vf-grid, embl-grid or vf-section-header element.
  • Ensure data-vf-js-navigation-on-this-page-container="true" is present on .vf-navigation__list.
  • Ensure each anchor link has a data-vf-js-navigation-on-this-page-link.

Nunjucks syntax

Depending on your environment you'll want to use render or include. As a rule of thumb: server-side use include, precompiled browser use render. If you're using vf-eleventy you should use include.

Using include

You'll need to pass a context object from your code or Yaml file (example), as well as the path to the Nunjucks template. Nunjucks' include is an abstraction of render and provides some additional portability.


{% set context fromYourYamlFile %}
- or -
{% set context = { 
"exampleMultiColumns" : "false",
"component-type" : "block",
"classModifier" : "global",
"navigation" : [object Object],[object Object],[object Object],[object Object],
 }
%}
{% include "../path_to/vf-navigation/vf-navigation.njk" %}

Using render

This approach is best for bare-bones Nunjucks environments, such as precompiled templates with the Nunjucks slim runtime where include is not be available.


{% render '@vf-navigation', {
  "exampleMultiColumns" : "false",
  "component-type" : "block",
  "classModifier" : "global",
  "navigation" : [object Object],[object Object],[object Object],[object Object],}
