The vf-breadcrumb component is a navigational item that can identify to the site visitor their location on the website. They are a visual representation of the site's heirachy.
The vf-breadcrumb component should follow the vf-global-header in the page layout.
It should list no more than three items, including the current page. Each link in the component is separated by a > chevron. The page you are on should display an 'active' state in the breadcrumbs which is bold with no underline.
The "Related" variant allows you to indicate related items as additional navigation to the page the site visitor is on. They should be placed inside the vf-breadcrumbs <nav> element and be a seperate unordered list.
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.
includeYou'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.
