老王-根据已选节点id删选树结构

      let selected = [8, 16, 4, 7, 18];
      const deepTree = (data) => {
        return data.filter((item) => {
          const findId = selected.find((child) => item.id === child);
          if (findId) {
            console.log(findId) // 4 8 16
            return true;
          } else if (item.childMenuList && item.childMenuList.length) {
            return deepTree(item.childMenuList).length;
          }
          return false;
        });
      };
