我正在尝试配置如何添加一个表单，每当你点击添加按钮。有人可以帮助我吗？我附加了一个jsfiddle，以便您可以完全理解我在说什么

我们将创建一个表单的克隆，并将其添加到容器div中。

function addForm() {
   var formsContainer = document.getElementById("formsContainer");
   var newForm = document.getElementById("form1").cloneNode(true);
   newForm.style.display = "block";
   formsContainer.appendChild(newForm);
 }

<div style="display: none;" id = "form1">

  <form action="" method="" id = "add-order-form">
  <div class="row add-order-info text-center">
    <div class="col"> 
      <div class="dropdown">
        <button type="button" class="btn dropdown-toggle" 
        data-bs-toggle="dropdown">
        Select...
        </button>
          <ul class="dropdown-menu">
            <li><a class="dropdown-item" href="#">Mouse</a></li>
            <li><a class="dropdown-item" href="#">Monitor</a></li> 
            <li><a class="dropdown-item" href="#">Keyboard</a></li>
          </ul>
        </div>
      </div>
   </div>
   </form>
</div>

 <div id="formsContainer"></div>

<button type="button" value ="Add Child" onclick="addForm();" id = "add-button">
Add
</button>

下面是JS的一个分支，它可以让代码正常工作：

你可以使用js side而不是HTML克隆。2我认为这将是一个理想的方法。

var formcounter = 0;
function setForms(){  
  $("#wrapperFormContainer").append( '<form action="" method=""   id="add-order-form'+ formcounter +'"><div>add-order-form'+formcounter+'</div></form>');
  formcounter++;
}

#wrapperFormContainer{
  display:inline-block;
  width:100%;
  background-color:green;
}
#wrapperFormContainer form{
  display:inline-block;
  margin: 5px;
  background-color:red;
  border:solid 1px #fff;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div id="wrapperFormContainer">
  
</div>
<button type="button" onclick="setForms()">Add form</button>
