I'm trying to close an element when another element collapses but I can't find an answer that works for me.

I update the structure using Bootstrap and JavaScript it doesn't look like the real deal. But when I collapse the first sub-menu (<div class="collapse list-group-sub-menu spacer" id="subMenu1">), I want to collapse the first sub-menu and second sub-menu as well. For my project the divisions are all in rows otherwise I already had a method.

• Could you add some HTML Code aswell? – NullDev Commented Apr 19, 2017 at 13:04

• How is .collapse implemented? – Yury Tarabanko Commented Apr 19, 2017 at 13:18
• @YuryTarabanko it's part of the bootstrap library and I use it to (as defined above) to toggle the collapse status. But I can't seem to get the value back if it's collapsed or not – B Zwikker Commented Apr 19, 2017 at 13:22
• If anyone has an idea without javascript it's fine aswell – B Zwikker Commented Apr 19, 2017 at 13:23

According to Docs bootstrap collapse use css classes to indicate state

.collapse hides content

.collapsing is applied during transitions

.collapse.show shows content

You can use .collapse:not(.show) selector to check if collapsible element is collapsed.

if($('#subMenu1').is('.collapse:not(.show)')) {
    // do smth
}

You could hide "child collapsible elements" when its parent is been hided, that is on('hidden.bs.collapse', function), see following snippet:

$("#collapse1").on('hidden.bs.collapse', function(){
  $("#collapse1 .collapse").collapse('hide');
});

  <script src="https://maxcdn.bootstrapcdn./bootstrap/3.3.7/js/bootstrap.min.js"></script>

<div class="panel-group">
  <div class="panel panel-default">
    <div class="panel-heading">
      <h4 class="panel-title">
        <a id="lnk1" data-toggle="collapse" data-target="#collapse1" href="#collapse1">Menu 1</a>
      </h4>
    </div>
    <div id="collapse1" class="panel-collapse collapse">
      <div class="panel panel-default">
          <h3 class="panel-title">
            <a data-toggle="collapse" href="#collapse2">Sub menu 1</a>
          </h3>
      </div>
      <ul class="list-group">
        <li class="list-group-item">
          <div id="collapse2" class="panel-collapse collapse">
            <ul class="list-group">
            <li class="list-group-item">Item 1</li>
            <li class="list-group-item">Item 2</li>
            </ul>
          </div>
        </li>
      </ul>
    </div>
  </div>
</div>

If you like a plain vanilla javascript solution (which you asked for originally...) here is a general approach could be adapted to your case.

I took the html markup from Bootstrap4 and added an id selector.

<button class="btn btn-lightgreen" type="button" id="collapsebutton" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">Button with data-target</button>
<div class="collapse" id="collapseExample">
<div class="card card-body">Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.
</div>

<script>
 var clickbutton = document.getElementById('collapsebutton');
 clickbutton.addEventListener('click', collapseclick);
 function collapseclick () {
   var closed =  this.getAttribute('aria-expanded');
   if (closed=='false') {
     alert("now open");
     //do stuff...
   }
 }
</script>
