          <div v-for="(item, index) in baseSizeTypeData" :key="index">
            <el-tree
              @node-click="handleNodeClick"
              :data="item.configMatterClasses"
              default-expand-all
              highlight-current
              :expand-on-click-node="false"
              :props="{ children: 'children', label: 'name' }"
              :render-content="renderContent"
            >
            </el-tree>
          </div>
