title: silviomoreto / bootstrap-select [title] attribute
body: <p>There is an attribute [multiple title] according silvio bootstrap-select documentation:</p>
  
  <p>Here is documentation:
  <a href="http://silviomoreto.github.io/bootstrap-select/" rel="nofollow">https://github.com/silviomoreto/bootstrap-select</a></p>
  
  <pre><code>&lt;select class="selectpciker" multiple title='Choose one of the following...'&gt;
  &lt;option&gt;1&lt;/option&gt;
  &lt;option&gt;1&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>It works well! But I need a single select ( not multiple ) . [title] attribute doesn't works without [multiple] attribute. </p>
  
  <p>I didn't find a single title attribute in silvio bootstrap-select documentation.</p>
  
  <p>Could anyone help me ?</p>
