title: TYPO3 form - select an option from select box with get parameter
body: <p>I'm trying to have a TYPO3 request form that is called from a simple link with a parameter, e.g.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>  &lt;a href="contact/inquiry/?tx_form[Product-line]=14"&gt;request&lt;/a&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>The TYPO3 form has a select box with some options:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;select id="field-10" name="tx_form[Product-line]"&gt;
          &lt;option value="11"&gt;Product 1&lt;/option&gt;
          &lt;option value="12"&gt;Product 2&lt;/option&gt;
          &lt;option value="13"&gt;Product 3&lt;/option&gt;
        &lt;/select&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>How can I preselect the option with a get parameter here?</p>
