    "@testing-library/react": "^13.4.0",
    "@testing-library/user-event": "^13.5.0",

Step 3: Include Bootstrap in the Project

In src/index.js, import Bootstrap’s CSS:

JavaScript

//index.js  import 'bootstrap/dist/css/bootstrap.min.css'; import React from 'react'; import ReactDOM from 'react-dom'; import './styles.css';  // optional CSS for extra styling import App from './App';  ReactDOM.render(<App />, document.getElementById('root'));

Step 4: Create a Dynamic Select Component with Form Submission in `App.js`

JavaScript

//App.js  import React, { useState } from 'react'; import { Form, Button } from 'react-bootstrap';  function App() {     const [selectedOption, setSelectedOption] = useState('');     const options = ['Option 1', 'Option 2', 'Option 3', 'Option 4'];      const handleSelectChange = (event) => {         setSelectedOption(event.target.value);     };      const handleSubmit = (event) => {         event.preventDefault();         alert(`You selected: ${selectedOption}`);     };      return (         <div className="container mt-5">             <h1>Dynamic Select with Form Submission</h1>             <Form onSubmit={handleSubmit}>                 <Form.Group controlId="dynamicSelect">                     <Form.Label>Select an Option</Form.Label>                     <Form.Control as="select" value={selectedOption} onChange={handleSelectChange}>                         <option value="">Choose...</option>                         {options.map((option, index) => (                             <option key={index} value={option.toLowerCase().replace(' ', '')}>                                 {option}                             </option>                         ))}                     </Form.Control>                 </Form.Group>                 <Button type="submit" variant="primary">Submit</Button>             </Form>             <p className="mt-3">Selected Option: {selectedOption}</p>         </div>     ); }  export default App;
