title: Selectpicker (bootstrap-select) doesn't work, shows a disabled menu?
body: <p>I'm trying to use selectpicker from Bootstrap-Select to make a multi-select dropdown menu. Here is what I have in my HTML file:</p>
  
  <pre><code>&lt;select class="selectpicker" multiple&gt;
      &lt;option&gt;Mustard&lt;/option&gt;
      &lt;option&gt;Ketchup&lt;/option&gt;
      &lt;option&gt;Relish&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>But this is what I get on my web app:</p>
  
  <p><a href="https://i.stack.imgur.com/6nUAN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6nUAN.png" alt="enter image description here"></a></p>
  
  <p>I can't hit the dropdown menu, it's disabled. How do I get this menu to be enabled?</p>
