title: Add an image file to existing javascript
body: <p>I am using a template with existing javascript.  The mobile menu "icon" is actually a dropdown that has the word "MENU" in it.  This is old style in my opinion and I'd like to change that to the standard 3 bars for a mobile menu. </p>
  
  <p>The section of the javascript that brings this up is:</p>
  
  <pre><code>if ($nav.is('ul,ol')) {
  
      if (settings.header) {
        $select.append(
          $('&lt;option/&gt;').text('MENU')
        );
      }
  </code></pre>
  
  <p>Is it possible to add .src("img/mobilemenubars.png") or something to this effect to replace the .text('MENU') section?  I can provide the entire javascript but I am not sure that is necessary.  Or is it?</p>
