title: How to enable the right click menu in the text box on my Google Chrome extension popup?
body: <p>I am creating a text box where the user will enter some input in my Google chrome extension popup.</p>
  
  <pre><code>&lt;div align="center"&gt;
  &lt;input type="text" id="textbox" size="25" style="height:30px;font-size:14pt;"/&gt;
  &lt;br&gt;
  &lt;script&gt;document.getElementById('textbox').focus()&lt;/script&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>But, to my surprise, when I right click inside the displayed textbox, no menu shows up!</p>
  
  <p>How can I enable the context menu?</p>
