This reference implementation of PatternFly is based on [Bootstrap v3](http://getbootstrap.com/). Think of PatternFly as a "skinned" version of Bootstrap with additional components and customizations.

<div id="{{include.id}}" class="input-group date">
  <input type="text" class="form-control bootstrap-datepicker" readonly><span class="input-group-addon"><span class="fa fa-calendar"></span></span>
</div>
<script>
  $('#{{include.id}}').datepicker({
    autoclose: true,
    orientation: "top auto",
    todayBtn: "linked",
    todayHighlight: true
  });
</script>
