bootstrap 4 collapse only one at a time doesn't work. but works in bootstrap 3

Question

I'm working with bootstrap 4.4.1. My goal is to expand accordion one panel at a time and close other panels which are previously open. I couldn't achieve this. I noticed one more issue, that my goal is achieved when bootstrap 3.3.1 is used. I mean accordion open one panel at a time is working in bootstrap 3.3.1, but not working in 4.4.1.

Bootstrap 4.4.1

<div class="panel-group" id="accordion1">
    <div class="panel panel-default">
        <div class="panel-heading accordion-toggle collapsed" data-toggle="collapse" data-parent="#accordion1" data-target="#collapseOne1">
             <h4 class="panel-title">Collapsible Group Item #1</h4>
        </div>
        <div id="collapseOne1" class="panel-collapse collapse">
            <div class="panel-body">...</div>
        </div>
    </div>
    <div class="panel panel-default">
        <div class="panel-heading accordion-toggle collapsed" data-toggle="collapse" data-parent="#accordion1" data-target="#collapseTwo1">
             <h4 class="panel-title">Collapsible Group Item #2</h4>
        </div>
        <div id="collapseTwo1" class="panel-collapse collapse">
            <div class="panel-body">...</div>
        </div>
    </div>
    <div class="panel panel-default">
        <div class="panel-heading accordion-toggle collapsed" data-toggle="collapse" data-parent="#accordion1" data-target="#collapseThree1">
             <h4 class="panel-title">Collapsible Group Item #3</h4>
        </div>
        <div id="collapseThree1" class="panel-collapse collapse">
            <div class="panel-body">...</div>
        </div>
    </div>
</div>

Is it feasible to achieve this on bootstrap 4.4.1? Thanks in advance

Answer 1

You need to set data-parent="#accordion1" property to div#collapseOne1, div#collapseTwo1 and div#collapseThree1 instead of your divs with class panel-title.

working example on codepen

You can also add class="accordion" to your wrapper (div#accordion1) and use cards to style your accordion. Refer to accordions

<div class="panel-group" id="accordion1">
  <div class="panel panel-default">
    <div class="panel-heading" data-toggle="collapse"  data-target="#collapseOne1">
      <h4 class="panel-title">Collapsible Group Item #1</h4>
    </div>
    <div id="collapseOne1" class="panel-collapse collapse show" data-parent="#accordion1">
      <div class="panel-body">Body 1</div>
    </div>
  </div>
  <div class="panel panel-default">
    <div class="panel-heading collapsed" data-toggle="collapse" data-target="#collapseTwo1">
      <h4 class="panel-title">Collapsible Group Item #2</h4>
    </div>
    <div id="collapseTwo1" class="panel-collapse collapse" data-parent="#accordion1" >
      <div class="panel-body">Body 2</div>
    </div>
  </div>
  <div class="panel panel-default">
    <div class="panel-heading" data-toggle="collapse"  data-target="#collapseThree1">
      <h4 class="panel-title">Collapsible Group Item #3</h4>
    </div>
    <div id="collapseThree1" class="panel-collapse collapse" data-parent="#accordion1">
      <div class="panel-body">Body 3</div>
    </div>
  </div>
</div>
