jQueryUI autocomplete in Bootstrap modal displaying underneath modal

Question

I have a jQueryUI autocomplete in a Bootstrap modal window. When I run it normally in the page it works fine, but when I try add it into the modal the list appears behind the modal, not in front.

I've tried variations of the following with no luck:

$("#myModal").css("z-index", "1500"); 
$("tags'.$fieldname.'").css("z-index", "5000");

In the modal:

data-backdrop="false"

Here is the source:

<!-- RFQ Modal -->
<div class="modal" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog" style="z-index:2000;">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>

      <div class="modal-body" data-backdrop="false"  >

      <script>
      $(function ps2() {        

      var availableTagsps2 = [
      {label:"3rd It Tech (IS# 20)", value:20},{label:"SeaBreeze Computers (IS# 14)", value:14},{label:"SeaBreeze Computers (IS# 14)", value:14},{label:"SeaBreeze Computers (IS# 14)", value:14},{label:"SeaBreeze Computers (IS# 14)", value:14},{label:"SeaBreeze Computers (IS# 14)", value:14},{label:"SeaBreeze Computers (IS# 14)", value:14} 

      ];

      $("#tagsps2").autocomplete({
           source: availableTagsps2

      });

  $( "#tagsps2" ).autocomplete({
            source: availableTagsps2,
            select: function ps2(event, ui) {
            var selectedObj = ui.item;
            $(this).val(selectedObj.label);
            $('input[name="ps2"]').val(selectedObj.value);

            return false;
        }

    });
/* $("#myModal").css("z-index","6000"); 
$("#tagsps2").css("z-index","20000");*/
  });

  </script>

  <input type="text" id="tagsps2"  required  AutoComplete="off" placeholder="Search..." 
  class="inputMed inline form-control input-med"  />
  <input type="hidden" name="ps2" value=""  />

        <div class="row" >
              <div class="col-md-6">
              <form role="form">
                  <div class="form-group" >

                    <!-- <input type="text" class="form-control" placeholder="Select client" required> -->
                  </div>

                  <button type="submit" class="btn btn-primary btn-lg">Submit</button>
                </form>
              </div>

              <div class="col-md-6">

                    <button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
                    <a href="dashboard.php?vrfq" class="light">View Sent RFQ's</a>
                    </button>
                </div>

        </div>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>

          </div>
        </div>
      </div>
    </div>
<!-- end modal -->

    <a href="#" data-toggle="modal" data-target="#myModal"><div class="RightCounter">&    nbsp;</div><h2>RFQ</h2></a>

Answer 1

Using Bootstrap 3.1.1 I found it sufficient just to add the following CSS to get the autocomplete to work.

.ui-autocomplete {
    z-index: 5000;
}

The ui-autocomplete class is attached to the UL which is used internally to construct the autocomplete. By giving it a crazy high z-index you effectively ensure it will be laid out above everything else in the page including the modal dialog.
