title: programmatically open a bootstrap select
body: <p>I need to programmatically <strong>open</strong> a <a href="http://silviomoreto.github.io/bootstrap-select/" rel="nofollow">bootstrap select</a>, not <strong>show</strong> like <a href="http://silviomoreto.github.io/bootstrap-select/#show" rel="nofollow">documentation</a> says 
  <br>(it affects displaying)</p>
  
  <p>It seems to be a missing method, so how can it be done?</p>
