The Fluid template

This generated menu can be used in Fluid like this:

EXT:examples/Resources/Private/Templates/ContentElements/DataProcLangMenu.html
<html data-namespace-typo3-fluid="true" xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers">
   <h2>Data in variable languageNavigation</h2>
   <f:debug inline="true">{languageNavigation}</f:debug>

   <h2>Output</h2>
   <f:if condition="{languageNavigation}">
      <ul id="language" class="language-menu">
         <f:for each="{languageNavigation}" as="item">
            <li class="{f:if(condition: item.active, then: 'active')}
                    {f:if(condition: item.available, else: ' text-muted')}">
               <f:if condition="{item.available}">
                  <f:then>
                     <a href="{item.link}" hreflang="{item.hreflang}"
                        title="{item.navigationTitle}">
                        <span>{item.navigationTitle}</span>
                     </a>
                  </f:then>
                  <f:else>
                     <span>{item.navigationTitle}</span>
                  </f:else>
               </f:if>
            </li>
         </f:for>
      </ul>
   </f:if>

</html>

Output

The array now contains information on all languages as defined in the site configuration. As the current page is not translated into German, the German language has the item.available set to false. It therefore does not get linked in the template.
