我正在尝试实现子菜单（嵌套菜单）。
值得一提的是，我正在使用 Hydra 组件，并且之前没有 Redux 的经验（因为这个特定问题，几天前开始学习它）。
我已按照material-ui 上提供的嵌套列表示例https://material-ui.com/demos/lists/#nested-list。以及教程来自https://marmelab.com/react-admin/Theming.html#using-a-custom-menu用于自定义菜单实现。
所以我有几个问题。
1）我可以有状态组件（MyMenu）仅用于处理菜单项的切换吗？
一个例子与react-admin无关，但它只是我的意思的例子。
import React, { Component } from "react";
import { connect } from "react-redux";
import { addArticle } from "../actions/index";
const mapDispatchToProps = dispatch => {
return {
addArticle: article => dispatch(addArticle(article))
};
};
class ConnectedForm extends Component {
constructor() {
super();
this.state = {
title: ""
};
this.handleChange = this.handleChange.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
}
handleChange(event) {
this.setState({ [event.target.id]: event.target.value });
}
handleSubmit(event) {
event.preventDefault();
const { title } = this.state;
const id = uuidv1();
this.props.addArticle({ title, id });
this.setState({ title: "" });
}
render() {
const { title } = this.state;
return (
<form onSubmit={this.handleSubmit}>
<div className="form-group">
<label htmlFor="title">Title</label>
<input
type="text"
className="form-control"
id="title"
value={title}
onChange={this.handleChange}
/>
</div>
<button type="submit" className="btn btn-success btn-lg">
SAVE
</button>
</form>
);
}
}
const Form = connect(null, mapDispatchToProps)(ConnectedForm);
export default Form;
2）如果没有，我可以通过在 store 中声明一个新状态来实现这一点，例如 open: false，然后使用自定义减速器来处理它。
3（奖金）。如果这不是问题，如果有人能给我正确的方向，我将不胜感激，首先要开始学习哪些东西，这样我就可以不那么痛苦地解决与这个令人惊叹的框架相关的问题:)
React-admin 演示现在展示了一种执行此操作的方法示例/demo/src/layout/Menu.js:
