Bootstrap Accordion Button Toggle "Data-Parent" Not Working

Bootstrap Accordion button toggle data-parent not working

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>

Bootstrap 3

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..

http://bootply.com/88288

<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#)

Bootstrap collapse data-parent not working

I couldn't get this to work either - this may be something in the Bootstrap JS related to the fact that you are using lists rather than divs?

So to get it to work, I had to override the click event. Based on this question here: Collapsible accordion doesn't work inside a dropdpwn-menu Bootstrap

I added an accordion-toggle class to each option link, and then added the following JavaScript to get it to work:

$(document).on('click', '.accordion-toggle', function(event) {
        event.stopPropagation();
        var $this = $(this);

        var parent = $this.data('parent');
        var actives = parent && $(parent).find('.collapse.in');

        // From bootstrap itself
        if (actives && actives.length) {
            hasData = actives.data('collapse');
            //if (hasData && hasData.transitioning) return;
            actives.collapse('hide');
        }

        var target = $this.attr('data-target') || (href = $this.attr('href')) && href.replace(/.*(?=#[^\s]+$)/, ''); //strip for ie7

        $(target).collapse('toggle');
});

This fiddle shows it in action.

Bootstrap 4 nested collapse data-parent not working

It's not working because the data-parent attribute should be the collapsible (.collapse) element, instead of the data-toggle (trigger) element...

bootstrap V4 accordion auto collapse not working

First of all you need include CSS:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

After that couple JS libraries:

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

And finally HTML:

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

      </h5>
    </div>

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