title: automatisation of options for select HTML
body: <p>I have an select field in html like</p>
  
  <pre><code>&lt;select&gt;
          &lt;option&gt;-&lt;/option&gt;
          &lt;option&gt;One&lt;/option&gt;
          &lt;option&gt;Two&lt;/option&gt;
          &lt;option&gt;Three&lt;/option&gt; 
  &lt;/select&gt;
  </code></pre>
  
  <p>But right now I type in the options manually. But the options should depend on an file I upload.
  So ideally I would create an list <code>list = [One,Two,Three]</code> (depends on file) and could create my options with that list? Is something like that even possible? Or is the only way of defining those options of an select field by typing them in in advance?</p>
