Bootstrap Accordion 在 React 中无法正常工作

Question

So I copy pasted the exact same code for Accordion from Bootstrap, but the style is completely different, and it doesn't function.

The code of About.js:

import React, { useState } from 'react'

export default function About() {

  return (
    <div class="accordion" id="accordionExample">
        <div class="accordion-item">
            <h2 class="accordion-header" id="headingOne">
            <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
                Accordion Item #1
            </button>
            </h2>
            <div id="collapseOne" class="accordion-collapse collapse show" aria-labelledby="headingOne" data-bs-parent="#accordionExample">
            <div class="accordion-body">
                <strong>This is the first item's accordion body.</strong> It is shown by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the <code>.accordion-body</code>, though the transition does limit overflow.
            </div>
            </div>
        </div>
        <div class="accordion-item">
            <h2 class="accordion-header" id="headingTwo">
            <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
                Accordion Item #2
            </button>
            </h2>
            <div id="collapseTwo" class="accordion-collapse collapse" aria-labelledby="headingTwo" data-bs-parent="#accordionExample">
            <div class="accordion-body">
                <strong>This is the second item's accordion body.</strong> It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the <code>.accordion-body</code>, though the transition does limit overflow.
            </div>
            </div>
        </div>
        <div class="accordion-item">
            <h2 class="accordion-header" id="headingThree">
            <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#collapseThree" aria-expanded="false" aria-controls="collapseThree">
                Accordion Item #3
            </button>
            </h2>
            <div id="collapseThree" class="accordion-collapse collapse" aria-labelledby="headingThree" data-bs-parent="#accordionExample">
            <div class="accordion-body">
                <strong>This is the third item's accordion body.</strong> It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the <code>.accordion-body</code>, though the transition does limit overflow.
            </div>
            </div>
        </div>
    </div>
  )

}

The code of App.js:

import About from './components/About';

function App() {
  return (
    <>
    <div className="container my-3">
      <About/>
    </div>
    </>
    )
}

export default App;

How it's supposed to look like: The bootstrap accordion

How it actually looks: The accordion on my React App

And I don't think there are any typos in importing it or in using it anywhere else. I also made sure to include the Bootstrap CSS link.

Answer 1

{/* The following line can be included in your src/index.js or App.js file*/}

import 'bootstrap/dist/css/bootstrap.min.css';

I think you are not using it the right way, you should read the docs for React Bootstrap, you're not supposed to copy everything with classnames and such, there are components that you can use that will do that for you, here's the example: react-bootstrap.github.io/components/accordion
