如何在ReactJS中制作一个可重用的下拉过滤器，这个过滤器是干的，可以在同一个组件中使用两次

import React, { Component } from 'react';

class DropdownFilter extends Component {
  constructor(props) {
    super(props);
    this.state = {
      options: props.options,
      selectedValue: ''
    };
  }

  handleChange = (event) => {
    this.setState({ selectedValue: event.target.value });
  }

  render() {
    const { options, selectedValue } = this.state;
    const filteredData = this.props.data.filter(item => item.category === selectedValue);

    return (
      <div>
        <select value={selectedValue} onChange={this.handleChange}>
          <option value="">All</option>
          {options.map(option => (
            <option key={option} value={option}>{option}</option>
          ))}
        </select>
        <ul>
          {filteredData.map(item => (
            <li key={item.id}>{item.name}</li>
          ))}
        </ul>
      </div>
    );
  }
}

export default DropdownFilter;

import React, { Component } from 'react';
import DropdownFilter from './DropdownFilter';

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [
        { id: 1, name: 'Item 1', category: 'Category A' },
        { id: 2, name: 'Item 2', category: 'Category B' },
        { id: 3, name: 'Item 3', category: 'Category A' },
        { id: 4, name: 'Item 4', category: 'Category C' },
      ],
      categories: ['Category A', 'Category B', 'Category C']
    };
  }

  render() {
    const { data, categories } = this.state;

    return (
      <div>
        <DropdownFilter data={data} options={categories} />
        <DropdownFilter data={data} options={categories} />
      </div>
    );
  }
}

export default App;
