In this menu definition, the second entry does not contain an `identifier`, so the `Identifier` method returns its `name` property instead:
|
||
|
|
|
||
|
|
{{< code-toggle file=hugo >}}
|
||
|
|
[[menus.main]]
|
||
|
|
identifier = 'about'
|
||
|
|
name = 'About'
|
||
|
|
pageRef = '/about'
|
||
|
|
weight = 10
|
||
|
|
|
||
|
|
[[menus.main]]
|
||
|
|
name = 'Contact'
|
||
|
|
pageRef = '/contact'
|
||
|
|
weight = 20
|
||
|
|
{{< /code-toggle >}}
|
||
|
|
|
||
|
|
This example uses the `KeyName` 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 (.KeyName | lower)) .Name }}</a></li>
|
||
|
|
{{ end }}
|
||
|
|
</ul>
|
||
|
|
```
|
||
|
|
|
||
|
|
In the example above, we need to pass the value returned by `.KeyName` through the [`lower`] function because the keys in the translation table are lowercase.
