vue中动态添加div

效果：

核心代码说明(样式代码可自行修改，详细代码请参照源码)：

<div v-for="(v,i) in list">
            <div class="form-group  m-form__group row" style="padding-top: 15px;padding-bottom: 15px;">
                <label class="col-form-label col-lg-2 col-sm-12">联系人类型 <span
                        style="color: #F00">*</span>
