## 最后实现效果 ##

![在这里插入图片描述][02233ed2ccd247d5aaa869a2e7013d67.png]

如图所示，这个弹窗的数据有三级，其中一级很好做，难在二级和三级，需要控制三级的样式相对于二级动态展示，点击二级，三级的div盒子宽度没办法显示一整行，只能展示那一列。所以最后实现效果需要根据二级进行绝对定位，由于绝对定位，三级盒子不占位，位置根据当前的选中行来计算，当前选中行的下一行设置一个`margin top`，然后`margintop`的高度动态获取。

## 主要代码 ##

<div class="right">
              <div class="right_box">
                <div v-for="array, index in convertList" :key="`array-${index}`"
                  :class="['row', currentRowIndex === index && isShowThree ? 'row_space' : '']">
                  <div class="text_box" v-for="item in array" :key="item.id">
                    <div class="text_icon flex" @click.stop="twoClick(item, index)"
                      :class="{ 'marginBottom': currentItemId === item.id }">
                      <img class="position_icon pointer" src="@/assets/image/position_jian.png" width="15" height="14" alt=""
                        v-if="currentItemId === item.id && isShowThree">
                      <img class="position_icon pointer" src="@/assets/image/position_jia.png" width="15" height="14" alt=""
                        v-else>
                      <div class="ellipsis" :class="{ 'relative_box': currentItemId === item.id }">{
        {
         item.displayName }}
                      </div>
                    </div>
                  </div>
                </div>
                
                <div v-if="currentRowIndex >= 0 && isShowThree" class="three_tree"
                  :style="{ top: `${currentRowIndex * 40 + 60}px` }">
                  <div>
                    <el-row :gutter="20">
                      <el-col class="three_item" v-for="item in threeItemList" :key="item.id" @click="threeClick(item)"
                        :span="6">
                        <div class="pointer" :class="{ 'three_selected': currentItemThree === item.id }">
                          {
        {
         item.displayName }}
                        </div>
                      </el-col>
                    </el-row>
                  </div>
                </div>
              </div>
            </div>

最重要的一个步骤就是将一维数组转化成二维数组，因为用一维数组直接循环盒子，得到的样式只能是按列来的，所以需要将数组处理成一行，就是四个（`index % 4 === 0`）

/**
     * 一维数组转换成展示的二维数组
     */
    const convertList = computed(() => {
        
      if (twoItemList.value && twoItemList.value.length) {
        
        return twoItemList.value.reduce((acc, cur, index) => {
        
          if (index % 4 === 0) {
         // 每行展示4个
            acc.push(twoItemList.value.slice(index, index + 4))
          }
          return acc
        }, [])
      } else {
        
        return []
      }
    })
