Vue v-for double nesting, delete the Div, of the child loop and retain the Div? of the parent loop

now I have a double for loop, which aims to delete the div (that is, the serial number of the following figure) of the subloop in the double loop. But how do you get labels, and delete its div?

HTML Code:
< div id= "dangerOperateDiv" >

    <div v-for="(d,index) in dangerOperate">
        <div class="layui-row" style="margin-top:8px;">
            <div class="layui-col-md12">
                <div class="layui-col-md3">
                    <div class="layui-col-md5">
                        <label class="layui-form-label" style="line-height:10px;float:right;"></label>
                    </div>
                </div>
            </div>
        </div>
        <div class="layui-row queryCriteria" style="margin-top:8px;">
            <div class="layui-col-md12">
                <div style="width:28%;float:left;">
                    <div style="float:left;position:relative;">
                        <input type="text" class="layui-input" style="width:227px;height:28px;position:relative;float:left;margin-left: 50px" v-model="d.name">
                        <div class="closeCircle" v-on:click="delThis(index)">
                            X
                        </div>
                    </div>
                    <div v-on:click="showNext(index)" style="float:left;">
                        <i class="layui-icon showIcon"
                           style="font-size: 20px; color: rgb(146,146,146);margin-left: 5px"></i>
                    </div>
                </div>
                <div v-show="d.isShow == true" style="background:rgba(200,200,200,0.5);width:72%;float:left;">
                    <div style="float:right;position:relative;z-index: 99">
                        <div class="closeCircle" v-on:click="delThat(index)">
                           X
                        </div>
                    </div>
                    <div v-for="(label,index) in d.labels">
                    <div class="layui-row layui-col-md12" style="background:-sharpffffff;border:1px solid -sharpdcdcdc">
                        <div class="layui-col-md3" style="float: left;margin-top: 10px;height: 40px;">
