TYPO3 - How can I display a Tag Search from tx_news into my Fluidtemplate?

Question

I'm using TYPO3 7.6.3 with the great News-Extension from Georg Ringer news 4.1.0 .

I need the Tag-Search from tx_news as a Select-Box, so I include the Plugin and change the Template /EXT:myext/Resources/Private/Extensions/News/Templates/Tag/List.html from a ul/li-List to the selectbox. This part is working fine!

But I need this select-box not as a Content Element, I need it at my Footer-Navigation, which I made with TypoScript. How can I use the tx_news-Template (Tag/List.html) into my Footer-Partial?

Here's the screen:

My version of the tag-list .. as a search box

Answer 1

I'v tried it like this ..

...
    20 = CONTENT
    20 {
        table = tx_news_domain_model_tag
        select {
            selectFields = tx_news_domain_model_tag.title
            orderBy = tx_news_domain_model_tag.title asc
            ### pid folder 'tags'
            pidInList = 32
        }
        renderObj = COA
        renderObj {
            10 = TEXT
            10.field = uid
            10.wrap = <option value="|">
            10.wrap.insertData = 1

            20 = TEXT
            20.field = title
            20.wrap = |</option>
            20.wrap.insertData = 1
        }
    }

    20.wrap = <form method="get" action="/index.php"><input type="hidden" name="id" value="17" /><select name="tx_news_pi1[overwriteDemand][tags]"><option value="" selected>Tag Suche</option>|</select></form>
...
