[twitter-bootstrap] Bootstrap: Collapse other sections when one is expanded

For Bootstrap v4.1

Add the data-parent attribute to the collapse elements instead on the button.

<div id="myGroup">
<button class="btn dropdown" data-toggle="collapse" data-target="#keys"><i class="icon-chevron-right"></i> Keys  <span class="badge badge-info pull-right">X</span></button>
<button class="btn dropdown" data-toggle="collapse" data-target="#attrs"><i class="icon-chevron-right"></i> Attributes</button>
<button class="btn dropdown" data-toggle="collapse" data-target="#edit"><i class="icon-chevron-right"></i> Edit Details</button>

<div class="accordion-group">
    <div class="collapse indent" id="keys"  data-parent="#myGroup">
        keys
    </div>

    <div class="collapse indent" id="attrs"  data-parent="#myGroup">
        attrs
    </div>

    <div class="collapse" id="edit"  data-parent="#myGroup">
        edit
    </div>
</div>
