title: HTML Forms: Radio buttons with text fields
body: <p>This seems like a simple problem, but how do I create a basic HTML form that has a series of radio button options, with the last one being a text field to fill in a custom response (i.e. "Other").</p>
  
  <p>What I have now:</p>
  
  <pre><code>    Reason given for stop? &lt;br&gt;
      &lt;input type="radio" name="reason" value="Fit Description"&gt;Fit Description&lt;br&gt;
      &lt;input type="radio" name="reason" value="Suspicious Behavior"&gt;Suspicious Behavior&lt;br&gt;
      &lt;input type="radio" name="reason" value="No Reason Given"&gt;No Reason Given&lt;br&gt;
      &lt;input type="radio" name="reason" value=""&gt;Other&lt;br&gt;
  </code></pre>
