Bootstrap 5 Accordion

What are Bootstrap Accordion?
Accordion is a vertically collapsing element to show and hide content via class changes.
Installation
Manual installation (zip package)
To take advantage of our Bootstrap images component and use them in your project, you first need to install the MDB 5 Free package
MDB CLI
Watch our Quick Start Tutorial to discover and use the full potential of MDB 5 and MDB CLI
NPM
Prerequisites
Before starting the project make sure to install Node LTS (12.x.x recommended).
Installation
To install MDB UI KIT in your project easily type the following command in the terminal:
npm i mdb-ui-kit
Importing JS modules
You can import the entire library or just individual modules:
import * as mdb from 'mdb-ui-kit'; // lib
import { Input } from 'mdb-ui-kit'; // module
Importing CSS file
To import MDB stylesheet please use the following syntax:
@import '~mdb-ui-kit/css/mdb.min.css';
Importing SCSS modules
You can also import individual SCSS modules. To do it properly, we recommend to copy them from the node_modules/mdb-ui-kit/src/scss location directly to your project and import in the same way as CSS files.
Webpack integration
You can significantly speed up the process of creating a new project based on Webpack using our Starter.
CDN
Installation via CDN is one of the easiest methods of integrating MDB UI KIT with your project. Just copy the latest compiled JS script tag and CSS link tag from cdnjs to the application.
Don't forget to add also Font Awesome and Roboto font if you need. Here's an example code:
CSS
<!-- Font Awesome -->
<link
  href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.1/css/all.min.css"
  rel="stylesheet"
/>
<!-- Google Fonts -->
<link
  href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700&display=swap"
  rel="stylesheet"
/>
<!-- MDB -->
<link
  href="https://cdnjs.cloudflare.com/ajax/libs/mdb-ui-kit/3.3.0/mdb.min.css"
  rel="stylesheet"
/>
JS
<!-- MDB -->
<script
  type="text/javascript"
  src="https://cdnjs.cloudflare.com/ajax/libs/mdb-ui-kit/3.3.0/mdb.min.js"
></script>
Customization
Basic example
HTML
<div class="accordion" id="accordionExample">
  <div class="accordion-item">
    <h2 class="accordion-header" id="headingOne">
      <button
        class="accordion-button"
        type="button"
        data-mdb-toggle="collapse"
        data-mdb-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-mdb-parent="#accordionExample"
    >
      <div class="accordion-body">
        <strong>This is the first 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 <strong>.accordion-body</strong>, 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-mdb-toggle="collapse"
        data-mdb-target="#collapseTwo"
        aria-expanded="false"
        aria-controls="collapseTwo"
      >
        Accordion Item #2

    </h2>
    <div

      class="accordion-collapse collapse"
      aria-labelledby="headingTwo"
      data-mdb-parent="#accordionExample"
    >
      <div class="accordion-body">

    >
      <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

      </div>
    </div>

</div>
Flush
Add .accordion-flush to remove the default background-color, some borders, and some rounded corners to render accordions edge-to-edge with their parent container.
