I am working on Bootstrap 4 Collapse. Wanted to collapse other sections when one is expanded
So far I did is:
<p>
<a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">
content 1
</a>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample2" aria-expanded="false" aria-controls="collapseExample2">
Content 2
</button>
</p>
<div class="collapse" id="collapseExample">
<div class="card card-body">
Content one here
</div>
</div>
<div class="collapse" id="collapseExample2">
<div class="card card-body">
Content 2 here
</div>
</div>

Make use of data-parent
attribute:
<div class="container" id="myGroup">
<p>
<a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">
content 1
</a>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample2" aria-expanded="false" aria-controls="collapseExample2">
Content 2
</button>
</p>
<div class="collapse" id="collapseExample" data-parent="#myGroup">
<div class="card card-body">
Content 1 here
</div>
</div>
<div class="collapse" id="collapseExample2" data-parent="#myGroup">
<div class="card card-body">
Content 2 here
</div>
</div>
</div>
I added the id
to your container and also added the data-parent
to your content sections, referencing this container through the id
.
just put data-parent="#element_parent",
example...
<a class="btn btn-primary" data-toggle="collapse" href="#colla1" role="button" aria-expanded="false" aria-controls="colla1">
content 1
</a>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#colla2" aria-expanded="false" aria-controls="colla2">
Content 2
</button>
<div class="collapse" id="colla1" data-parent="#element_parent">
<nav
your content 1 here
</nav>
</div>
<div class="collapse" id="colla2" data-parent="#element_parent">
<nav
your content 2 here
</nav>
</div>
