Previous/Next navigation in Hugo with custom order based on param / attribute

This gist let's you return previous/next pages based on a frontmatter parameter in Hugo. In this exmaple, the frontmatter parameter is called position, where lower positions come first.

This prev / next navigation is looping: if there is no "next >" entry anymore, the first entry of the collection will be linked. Same for "< prev": if there is no previous element, the last element of the collection will be linked.

<div class="nav-prev-next">
    {{ $currentSection := (($.Site.GetPage "section" .Section).Pages.ByParam "position") }}
