Identifier	Returns the `identifier` property of the given menu entry.			functions_and_methods returnType signatures string MENUENTRY.Identifier

The Identifier method returns the identifier property of the menu entry. If you define the menu entry automatically, it returns the page's section.

{{< code-toggle file=hugo >}} menus.main identifier = 'about' name = 'About' pageRef = '/about' weight = 10

menus.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:

<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.
