TypoScript

Using the LanguageMenuProcessor the following scenario is possible:

        EXT:examples/Configuration/TypoScript/DataProcessors/Processors/LanguageMenuProcessor.typoscript
    

tt_content {
   examples_dataproclang =< lib.contentElement
   examples_dataproclang {
      templateName = DataProcLangMenu
      dataProcessing.10 = TYPO3\CMS\Frontend\DataProcessing\LanguageMenuProcessor
      dataProcessing.10 {
         languages = auto
         as = languageNavigation
      }
   }
}

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.
