For formatting in three columns a long list of items in a “Derived terms” section (without having to hack the related terms template with a {{rel-top3|Derived terms}}, though that's still what this template does for you internally in order to automatically keep them consistent). The only argument is an optional gloss (defaults to “Derived terms”):

Note: This template now uses CSS columns so {{der-mid3}} is no longer needed.

====Derived terms====
{{der-top3|optional gloss (defaults to “Derived terms”)}}
...
{{der-bottom}}
