Javascript 编程隐藏引导手风琴

在我的代码中，我使用引导手风琴作为额外选项。单击“开始”时，我想折叠（关闭）它。我试过了

    $('#accordion2').collapse({
        hide: true
    });

但手风琴先关上，然后再打开。第二次单击“不要再执行任何操作”。我错过了什么？正如在引导文档中所写，我使用数据父对象来关闭它。 代码是：

  <div id="accordion2" style="width:802px;">
      <div class="card">
        <div class="card-header" id="headingImgOne">
          <h5 class="mb-0">
            <button class="btn btn-link" data-toggle="collapse" data-target="#collapseImgOne" aria-expanded="true" aria-controls="collapseImgOne">
              Testrun Optionen
            </button>
          </h5>
        </div>

        <div id="collapseImgOne" class="collapse" aria-labelledby="headingImgOne" data-parent="#accordion2">
          <div class="card-body">

             <div class="form-group row">
               <label for="text" class="col-4 col-form-label">Server</label>
               <div class="col-7">
                 <div class="input-group">

您能给我们看一下您的完整html代码吗？我已经为手风琴添加了部分。
