[parameterEstimation]

Collapse works fine if site.min.jsis removed, but when added collapse only opens but don't close.

<a data-toggle="collapse" href="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
  Schedules
</a>
<div class="collapse" id="collapseExample">
  <ul class="list-group app-submenu-list-group">
      <li class="list-group-item"><a href="#">Work</a></li>
      <li class="list-group-item"><a href="#">Lunch</a></li>
       <li class="list-group-item"><a href="#">Breaks</a></li>
    </ul>
</div>
