html - Bootstrap Accordion button toggle "data-parent" not working

Question

I'm trying to create an accordion using Bootstrap 3 using the button collapsible with the data attribute, without the accordion markup. It just looks more cleaner to me.

However I cannot make the data-parent attribute to work. I want when opening a question, all others to close. I'm reading the docs ( http://getbootstrap.com/javascript/#collapse-usage ) but still cannot get it to work.

I'm using the following code:

<div class="accordion" id="myAccordion">
    <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">
    <p>Etiam posuere quam ac quam. Maecenas aliquet accumsan leo. Nullam dapibus fermentum ipsum. Etiam quis quam. Integer lacinia. Nulla est.</p>
    </div>
    <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">
    <p>Etiam posuere quam ac quam. Maecenas aliquet accumsan leo. Nullam dapibus fermentum ipsum. Etiam quis quam. Integer lacinia. Nulla est.</p>
    </div>
    <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">
    <p>Etiam posuere quam ac quam. Maecenas aliquet accumsan leo. Nullam dapibus fermentum ipsum. Etiam quis quam. Integer lacinia. Nulla est.</p>
    </div>
</div>

Here is the JSFiddle: http://jsfiddle.net/twinsen/AEew4/

I'll be very happy if someone points to me where I'm making a mistake :

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..

<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#)
