title: Google My Maps embed - expand layer filter
body: <p>I'm embedding a Google "My Maps" like this one: <a href="http://borgensystems.com/contact-us/" rel="nofollow">http://borgensystems.com/contact-us/</a>. In the top left corner, there's an expandable filter to turn layers off and on and click on them.</p>
  
  <p>Is there a way to expand this by default on page load?</p>
