`safeURL` declares the provided string as a "safe" URL or URL substring (see [RFC 3986]). A URL like `javascript:checkThatFormNotEditedBeforeLeavingPage()` from a trusted source should go in the page, but by default dynamic `javascript:` URLs are filtered out since they are a frequently exploited injection vector.

The following examples use a [site `config.toml`][configuration] with the following [menu entry][menus]:

The following is an example of a sidebar partial that may be used in conjunction with the preceding front matter example:
{{< code file="layouts/partials/bad-url-sidebar-menu.html" copy="false" >}}
{{< code file="layouts/partials/bad-url-sidebar-menu.html" copy=false >}}

<li><a href="{{ .URL }}">{{ .Name }}</a></li>
<li><a href="{{ .URL }}">{{ .Name }}</a></li>
{{ end }}
</ul>

This partial would produce the following HTML output:
{{< output file="bad-url-sidebar-menu-output.html" >}}
```html
