Javascript 以递归方式在项目数组中实现搜索：React JS

我使用一个对象数组来递归地绘制一棵树.我能够调出具有所有展开折叠相关功能的树.我在某种程度上实现了在整个树中进行搜索的搜索功能.如果匹配了叶子，我会显示展开到该 node 的所有 node .当搜索中间 node 或根 node 时，我应该显示它处于折叠状态，然后可以展开它

但是，当我搜索第一级或中间父 node 时，搜索结果是正确的，但当我试图打开它的子 node 时，结果是空的.此外，当我搜索任何父母时，图标似乎都会展开.

例如，当我搜索Category1时，树显示Category1带有展开的图标(它本应处于折叠状态)，而当我试图展开它的空图标时. 当我搜索Applications时，树显示了从类别1到应用程序的右侧层次 struct ，但应用程序将处于展开状态，并且那里也没有显示任何子项.

有人能告诉我我做错了什么吗？

到目前为止我try 过的代码

import React, { useState } from "react";
import "./styles.css";
import { Node } from "./Node";

const DrawnTree = ({ treeData, currentActive, setCurrentActive }) => {
  const [search, setSearch] = useState("");

  const containsNodesWithTerm = (nodes, searchTerm) => {
    const ids = [];
    const _traverse = (nodes, searchTerm) => {
      nodes.forEach((node) => {
        if (node.name.toUpperCase().includes(searchTerm.toUpperCase())) {
          ids.push(node.key);
        }
        if (node.nodes.length) {
          _traverse(node.nodes, searchTerm);
        }
      });
    };
    _traverse(nodes, searchTerm);
    return ids.length;
  };

  const filterNodes = (nodes, searchTerm = "") => {
    const _filter = (nodes, searchTerm) => {
      nodes.forEach((node) => {
        if (
          node.name.toUpperCase().includes(searchTerm.toUpperCase()) ||
          containsNodesWithTerm(node.nodes, searchTerm)
        ) {
          node.visible = true;
          node.opened = true;
        } else {
          node.visible = false;
        }
        if (!searchTerm) {
          node.opened = false;
        }
        if (node.nodes.length) {
          _filter(node.nodes, searchTerm);
        }
      });
    };
    _filter(nodes, searchTerm);
    return nodes;
  };

  const filteredTree = filterNodes(treeData, search);

  return (
    <div>
      <input type="text" onChange={(e) => setSearch(e.target.value)} />
      <div className="tree-list-section">
