崩溃不适用于模态

Question

在模态中，我试图以可折叠的形式连续添加3个文本字段。有一个名为add another的按钮，如果我点击那3个文本框应显示在第二行。我尝试使用模式中的#collapse示例，但它不起作用。流，机构和传递的年龄应该是点击添加按钮时的合并。

  <!-- Modal -->
  <div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">

  <!-- Modal content-->
  <div class="modal-content">
    <div class="modal-body">
      <div class="panel panel-default">
        <div class="panel-body">
          <button type="button" class="close" data-dismiss="modal">
            <font color="black">
              <a href="hrtoolkit.html" style="color: darkred">
                <span style="color: darkred;">&times;</span>
              </a>
            </font>
          </button>

它正在工作，请看这个例子

问题是你在表格中使用了div标签。只需在tr中传递崩溃类class class =“collapse”id =“collapseExample”

<tr class="collapse" id="collapseExample">
   <td class="outside" style="border-style: none; border-bottom-style: none; ">Stream
    <input type="text" class="form-control" placeholder="Stream" />
   </td>
   <td class="outside" style="border-style: none; border-bottom-style: none;">Institution
     <input type="text" class="form-control" placeholder="Institution" />
   </td>
   <td class="outside" style="border-style: none; border-bottom-style: none;">Yr of Passing
    <input type="date" class="form-control" id="resizedTextbox" placeholder="Yr of Passing" />
   </td>
 </tr>
