-The `Reverse` method returns the given menu, reversing the sort order of its entries.
-
-Consider this menu definition:
-
-{{< code-toggle file=hugo >}}
-[[menus.main]]
-name = 'Services'
-pageRef = '/services'
-weight = 10
-
-[[menus.main]]
-name = 'About'
-pageRef = '/about'
-weight = 20
-
-[[menus.main]]
-name = 'Contact'
-pageRef = '/contact'
-weight = 30
-{{< /code-toggle >}}
-
-To sort the entries by name in descending order:
-
-```go-html-template
-<ul>
-  {{ range .Site.Menus.main.ByName.Reverse }}
-    <li><a href="{{ .URL }}">{{ .Name }}</a></li>
-  {{ end }}
-</ul>
-```
-
-Hugo renders this to:
-
-```html
-<ul>
-  <li><a href="/services/">Services</a></li>
-  <li><a href="/contact">Contact</a></li>
-  <li><a href="/about/">About</a></li>
-</ul>
-```
