And this template:

go-html-template

{{ range .Ancestors }}
  <a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
{{ end }}

On the November 2023 auctions page, Hugo renders:

html

<a href="/auctions/2023-11/">Auctions in November 2023</a>
<a href="/auctions/">Auctions</a>
<a href="/">Home</a>

In the example above, notice that Hugo orders the ancestors from closest to furthest. This makes breadcrumb navigation simple:

go-html-template

<nav aria-label="breadcrumb" class="breadcrumb">
  <ol>
    {{ range .Ancestors.Reverse }}
      <li>
        <a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
      </li>
    {{ end }}
    <li class="active">
      <a aria-current="page" href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
    </li>
  </ol>
</nav>

With some CSS, the code above renders something like this, where each breadcrumb links to its page:

text

Home > Auctions > Auctions in November 2023 > Auction 1
