    let arr = Array.from(indexArray);
    for (let i = 0, len = data.length; i < len; i++) {
      arr.push(data[i]);
      if (data[i].id === id) {
        return arr;
      }
      let children = data[i].childMenu;
      if (children && children.length) {
        let result = this.findIndexArray(children, id, arr);
        if (result) {
          return result;
        }
      }
      arr.pop();
    }
  },
