 <el-cascader
              v-model="listType"
              :options="listTypeArr"
              :props="dialogProps"
              clearable
              size="mini"
              style="width: 220px"
              @change="changelistType"
            ></el-cascader>
dialogProps: {
        expandTrigger: "hover",
        value: "id",
        label: "categoryName",
        children: "children",
        emitPath: false,
      },
1、把:checkStrictly=true去掉
2、当该节点没有子节点时，数据结构中就不要children就可以了

将el-cascader的show-all-levels属性设置为false   :show-all-levels="false"
