 ### Example: List Tags in a Single Page Template

+{{< new-in "0.65.0" >}}

+```go-html-template

+<ul>

+    {{ range (.GetTerms "tags") }}

+        <li><a href="{{ .Permalink }}">{{ .LinkTitle }}</a></li>

+   {{ end }}

+</ul>

+```

+Before Hugo 0.65.0 you needed to do something like this:

 ```go-html-template

 {{ $taxo := "tags" }} <!-- Use the plural form here -->

 <ul id="{{ $taxo }}">
