How to make a Bootstrap accordion collapse when clicking the header div?

Question

In a Bootstrap accordion, instead of requiring a click on the a text, I want to make it collapse when clicking anywhere in the panel-heading div.

Answer 1

Here's a solution for Bootstrap4. You just need to put the card-header class in the a tag. This is a modified from an example in W3Schools.

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>

<div class="container">
  <div id="accordion">
    <div class="card">
      <a class="card-link card-header" data-toggle="collapse" href="#collapseOne" >
        Collapsible Group Item #1
      </a>
      <div id="collapseOne" class="collapse" data-parent="#accordion">
        <div class="card-body">
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </div>
      </div>
    </div>
    <div class="card">
      <a class="collapsed card-link card-header" data-toggle="collapse" href="#collapseTwo">
        Collapsible Group Item #2
      </a>
      <div id="collapseTwo" class="collapse" data-parent="#accordion">
        <div class="card-body">
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </div>
      </div>
    </div>
    <div class="card">
      <a class="card-link card-header" data-toggle="collapse" href="#collapseThree">
        Collapsible Group Item #3
      </a>
      <div id="collapseThree" class="collapse" data-parent="#accordion">
        <div class="card-body">
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </div>
      </div>
    </div>
  </div>
</div>

I've noticed a couple of minor flaws in grim's jsfiddle.

To get the pointer to change to a hand for the whole of the panel use:

.panel-heading {
   cursor: pointer;
}

I've removed the <a> tag (a style issue) and kept data-toggle="collapse" data-parent="#accordion" data-target="#collapse..." on panel-heading throughout.

I've added a CSS method for displaying chevron, using font-awesome.css in my jsfiddle:

Answer 3

Another way is make your <a> full fill all the space of the panel-heading. Use this style to do so:

.panel-title a {
    display: block;
    padding: 10px 15px;
    margin: -10px -15px;
}

Check this demo (http://jsfiddle.net/KbQyx/).

Then when you clicking on the heading, you are actually clicking on the <a>.

Answer 5

Actually my panel had this collapse state arrow icon and I tried other answers in this post , but icon position changed, so here is the solution with collapse state arrow icon.

Add this Custom CSS

 .panel-heading 
  {
   cursor: pointer;
   padding: 0;
  }

 a.accordion-toggle 
 {
  display: block;
  padding: 10px  15px;
 }

Credit's goes to this post answerer.

Hope helps.

Answer 6

All you need to do is to to use...

• data-toggle="collapse"
• data-target="#ElementToExpandOnClick"

...on the element you want to click to trigger the collapse/expand effect.

The element with data-toggle="collapse" will be the element to trigger the effect. The data-target attribute indicates the element that will expand when the effect is triggered.

Optionally you can set the data-parent if you want to create an accordion effect instead of independent collapsible, e.g.:

• data-parent="#accordion"

I would also add the following CSS to the elements with data-toggle="collapse" if they aren't <a> tags, e.g.:

.panel-heading {
    cursor: pointer;
}

Here's a jsfiddle with the modified html from the Bootstrap 3 documentation.
