Bootstrap Accordion button toggle "data-parent" not working

Note, not only there is dependency on .panel, it also has dependency on the DOM structure.

Make sure your elements are structured like this:

    <div id="parent-id">
        <div class="panel">
            <a data-toggle="collapse" data-target="#opt1" data-parent="#parent-id">Control</a>
            <div id="opt1" class="collapse">
...

It's basically what @Blazemonger said, but I think the hierarchy of the target element matters too. I didn't finish trying every possibility out, but basically it should work if you follow this hierarchy.

FYI, I had more layers between the control div & content div and that didn't work.


Bootstrap 3

Try this. Simple solution with no dependencies.

$('[data-toggle="collapse"]').click(function() {
  $('.collapse.in').collapse('hide')
});

As Blazemonger said, #parent, .panel, and .collapse have to be direct descendants. However, if you can't change your HTML, you can do a workaround using bootstrap events and methods with the following code:

$('#your-parent .collapse').on('show.bs.collapse', function (e) {
    var actives = $('#your-parent').find('.in, .collapsing');
    actives.each( function (index, element) {
        $(element).collapse('hide');
    })
})

Bootstrap 4

Use the data-parent="" attribute on the collapse element (instead of the trigger element)

<div id="accordion">
  <div class="card">
    <div class="card-header">
      <h5>
        <button class="btn btn-link" data-toggle="collapse" data-target="#collapseOne">
          Collapsible #1 trigger
        </button>
      </h5>
    </div>
    <div id="collapseOne" class="collapse show" data-parent="#accordion">
      <div class="card-body">
        Collapsible #1 element
      </div>
    </div>
  </div>
  ... (more cards/collapsibles inside #accordion parent)
</div>

See this issue on GitHub: https://github.com/twbs/bootstrap/issues/10966

There is a "bug" that makes the accordion dependent on the .panel class when using the data-parent attribute. To workaround it, you can wrap each accordion group in a 'panel' div..

<div class="accordion" id="myAccordion">
    <div class="panel">
        <button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#collapsible-1" data-parent="#myAccordion">Question 1?</button>
        <div id="collapsible-1" class="collapse">
            ..
        </div>
    </div>
    <div class="panel">
        <button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#collapsible-2" data-parent="#myAccordion">Question 2?</button>
        <div id="collapsible-2" class="collapse">
            ..
        </div>
    </div>
    <div class="panel">
        <button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#collapsible-3" data-parent="#myAccordion">Question 3?</button>
        <div id="collapsible-3" class="collapse">
           ...
        </div>
    </div>
</div>

Edit

As mentioned in the comments, each section doesn't have to be a .panel. However...

  • .panel must be a direct child of the element used as data-parent=
  • each accordion section (data-toggle=) must be a direct child of the .panel (http://www.bootply.com/AbiRW7BdD6#)
