Angular6 and Bootstrap4 collapsible div does not work

Question

There is accordion control provided with bootstrap4 https://getbootstrap.com/docs/4.0/components/collapse/#accordion-example

When I try to use this with my angular 6 app , it does not collapse. There is no error in the browser but it does not work. Any idea on this one ?

html

<div class="accordion" id="accordionExample">
  <div class="card">
    <div class="card-header" id="headingOne">
      <h5 class="mb-0">
        <button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
          Collapsible Group Item #1
        </button>
      </h5>
    </div>

    <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
      <div class="card-body">

Answer 1

Your code works perfectly fine for me.

Please find the below configurations

package.json

{
"bootstrap": "^4.1.3",
"popper.js": "^1.14.3",
"jquery": "3.3.1"
}

angular.json

"styles": [
              "src/styles.scss",
              "node_modules/bootstrap/dist/css/bootstrap.min.css"
            ],
            "scripts": [
              "node_modules/jquery/dist/jquery.min.js",
              "node_modules/bootstrap/dist/js/bootstrap.min.js"
            ]

You need to include jQuery for many of the components in bootstrap to function.

Checkout this pen, if you comment jQuery, collpase does not work, when you uncomment it works.

From bootstrap docs

Many of our components require the use of JavaScript to function. Specifically, they require jQuery, Popper.js, and our own JavaScript plugins. Place the following s near the end of your pages, right before the closing tag, to enable them. jQuery must come first, then Popper.js, and then our JavaScript plugins.

The bootstrap package you've included does not contain jQuery. From npm,

Bundled JS files (bootstrap.bundle.js and minified bootstrap.bundle.min.js) include Popper, but not jQuery.
