+
+The `Identifier` method returns the `identifier` property of the menu entry. If you define the menu entry [automatically], it returns the page's section.
+
+[automatically]: /content-management/menus/#define-automatically
+
+{{< code-toggle file=hugo >}}
+[[menu.main]]
+identifier = 'about'
+name = 'About'
+pageRef = '/about'
+weight = 10
+
+[[menu.main]]
+identifier = 'contact'
+name = 'Contact'
+pageRef = '/contact'
+weight = 20
+{{< /code-toggle >}}
+
+This example uses the `Identifier` method when querying the translation table on a multilingual site, falling back the `name` property if a matching key in the translation table does not exist:
+
+```go-html-template
+<ul>
+  {{ range .Site.Menus.main }}
+    <li><a href="{{ .URL }}">{{ or (T .Identifier) .Name }}</a></li>
+  {{ end }}
+</ul>
+```
+
+{{% note %}}
+In the menu definition above, note that the `identifier` property is only required when two or more menu entries have the same name, or when localizing the name using translation tables.
