getAvailableLanguages

Sequence getAvailableLanguages()

Returns the available languages for the current document as sequence. These sequence can be used for creating links for selecting the language:

<ul class="language-selector">
    <#list Lang.getAvailableLanguages()?sort as lang>
        <li class="${(lang==negotiatedLanguage)?then('selected', '')}">${lang}</li>
    </#list>
</ul>

This example uses the list directive from Freemarker to iterate over the available languages returned by getAvailableLanguages The Freemarker build-in ?then is used together with the negotiatedLanguage variable to check if the curent language is the selected language. If this is the case a CSS class is added to the HTML.
