title: Sort text in Option Button
body: <p>I have an option button with some values</p>
  
  <pre><code>Scotland
  Switzerland
  England
  </code></pre>
  
  <p>I would like to sort these lines alphabetically.
  How can I do that?</p>
  
  <pre><code>sort the text of button btn_type ascending(each)
  </code></pre>
  
  <p>or some variation of that does not work.    </p>
