html – Bootstrap multi-select – 使用Group Labels过滤问题

我在Rails Web应用程序中使用 Bootstrap (2.3.2) multiSELEct.我在multlectlect中使用的功能如下所示：

<script type="text/javascript">
  $(function() { 
    $('#coder_prod_SELEct_client').multiSELEct({
      includeSELEctAllOption: true,enableCaseInsensitiveFiltering: true,numberDisplayed: 0,nonSELEctedText: 'SELEct Facility',maxHeight: 450
    });
  });
</script>

以下是HTML代码：

<div id="coder_prod_facilities_for_SELEct">
    <SELEct name="facilitY[]" multiple="multiple" id="coder_prod_SELEct_facility" style="display: none;">
        <option value="multiSELEct-all"> SELEct all</option>
        <optgroup label="Group 1">
            <option value="114">Ancillary</option>
            <option value="115">Inpatient</option>
            <option value="117">Emergency</option>
        </optgroup>
        <optgroup label="Group 2">
            <option value="80">Inpatient</option>
            <option value="81">SS Surgery</option>
            <option value="90">Emergency</option>
        </optgroup>
        <optgroup label="Group 3">
            <option value="73">Inpatient</option>
            <option value="75">Observation</option>
            <option value="76">SS Surgery</option>
            <option value="77">Ancillary</option>
        </optgroup>
    </SELEct>

    <div class="btn-group">
        <button data-toggle="dropdown" class="multiSELEct dropdown-toggle btn btn-default" type="button" title="SELEct Facility">
            SELEct Facility
            <b class="caret"></b>
        </button>
        <ul class="multiSELEct-container dropdown-menu" style="max-height: 450px; overflow-y: auto; overflow-x: hidden;">
            <div class="input-group">

</div>

您可以在下面看到默认的视图/ HTMl.

您可以看到每个组下面都有类似的元素.例如,当我使用值’inpatient’进行过滤时,它显示的结果如下面的附件所示.

但是,每个过滤的“住院病人”值都属于不同的组,所有值都应该显示在它的组名称顶部!!,但事实并非如此.

有谁可以帮我识别并解决问题？
