使用Angular的时候如何避免破坏HTML结构？

Question

代码如下：

<div class="weui-cells lists">
        <div class="weui-cell">
          <div class="weui-cell__bd ">
            <p>患儿姓名:</p>
          </div>
          <div class="weui-cell__ft">王xx</div>
        </div>
        <div class="weui-cell">
          <div class="weui-cell__bd ">
            <p>出生日期:</p>
          </div>
          <div class="weui-cell__ft">2018-01-21</div>
        </div>
        <div class="weui-cell weui-cell_select weui-cell_select-after">
          <div class="weui-cell__hd">
            <label for="" class="weui-label">民族:</label>
          </div>
          <div class="weui-cell__bd">
            <select class="weui-select" name="select2">
              <option selected="true" disabled="true">请选择</option>
              <option value="1">汉</option>
              <option value="2">其他</option>
            </select>
          </div>
        </div>
</div>

我想提取中间的元素做成动态表单，其中<div class="weui-cells lists">一部分作为外层，然后遍历里面的部分，暂时是这样写的：

<div [formGroup]="form">
  <div [ngSwitch]="option.controlType">
    <!--span-->
    <div *ngSwitchCase="'span'" class="weui-cell">
      <div class="weui-cell__bd ">
        <p>{{option.label}}:</p>
      </div>
      <div class="weui-cell__ft">王xx</div>
    </div>
    <!--input-->
    <!--select-->
    <div *ngSwitchCase="'select'" class="weui-cell weui-cell_select weui-cell_select-after">
      <div class="weui-cell__hd">
        <label for="" class="weui-label">民族:</label>
      </div>
      <div class="weui-cell__bd">
        <select class="weui-select" name="select2">
          <option selected="true" disabled="true">请选择</option>
          <option value="1">汉</option>
          <option value="2">其他</option>
        </select>
      </div>
    </div>

  </div>
</div>

这其中最外层的两个div： <div [formGroup]="form"> <div [ngSwitch]="option.controlType"> 破坏了html结构，导致样式出现错误，请问我该如何修改才能让最外层的div不占用html标签呢？

Answer 1

<ng-container [formGroup]="form"></ng-container>

<ng-container [ngSwitch]="option.controlType"><ng-container>

Answer 2

前面写了一些tips, 可以参考下。
ng-content/ng-container
