title: Material Design Lite - Programatically Open and Close Toast
body: <p>I would like to open and close MDL toast rather than use the timeout property as indicated in the <a href="https://www.getmdl.io/components/index.html#snackbar-section" rel="nofollow">MDL usage guide</a>.  The reason is that I want the toast to remain while geolocation is occuring, which sometimes takes 10+ seconds and other times happens in 1 second.</p>
  
  <p>Any idea how this could be done?</p>
