Welcome to our comprehensive guide on how to animate or anchor Bootstrap 4 accordion to its respective title when clicking its button! In this article, we’ll dive into the world of Bootstrap 4 accordions and explore the various methods to achieve this functionality. So, buckle up and let’s get started!
What is Bootstrap 4 Accordion?
Before we dive into the implementation, let’s quickly cover the basics of Bootstrap 4 accordions. An accordion is a component that displays content in a collapsible manner, allowing users to expand or collapse sections as needed. Bootstrap 4 provides a built-in accordion component that can be easily integrated into your web application.
Why Animate or Anchor Accordion to its Respective Title?
Animating or anchoring the accordion to its respective title when clicking its button provides a better user experience. When a user clicks on an accordion button, they expect the content to be displayed immediately. By animating or anchoring the accordion, you can create a seamless transition between the button click and the content display. This enhances the overall usability and engagement of your web application.
Method 1: Animating the Accordion using CSS Transitions
One way to animate the accordion is by using CSS transitions. This method is simple and doesn’t require any JavaScript code. Let’s get started!
Step 1: Add the Accordion HTML Markup
<div id="accordionExample">
<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">
Collapsible Group Item #1
</button>
</h5>
</div>
<div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
<div class="card-body">
Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch.
</div>
</div>
</div>
<div class="card">
<div class="card-header" id="headingTwo">
<h5 class="mb-0">
<button class="btn btn-link" data-toggle="collapse" data-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
Collapsible Group Item #2
</button>
</h5>
</div>
<div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordionExample">
<div class="card-body">
Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch.
</div>
</div>
</div>
</div>Step 2: Add CSS Transition Styles
.collapse {
transition: height 0.5s;
}
.collapse.show {
height: 100%;
}
.collapse:not(.show) {
height: 0;
}In this example, we’ve added a CSS transition effect to the `.collapse` class, which animates the height property when the accordion is expanded or collapsed. The `.collapse.show` class is used to set the height to 100% when the accordion is expanded, and the `.collapse:not(.show)` class is used to set the height to 0 when the accordion is collapsed.
Method 2: Animate the Accordion using jQuery
If you prefer a JavaScript-based solution, you can use jQuery to animate the accordion. This method provides more flexibility and control over the animation effect.
Step 1: Add the Accordion HTML Markup
<div id="accordionExample">
<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">
Collapsible Group Item #1
</button>
</h5>
</div>
<div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
<div class="card-body">
Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch.
</div>
</div>
</div>
<div class="card">
<div class="card-header" id="headingTwo">
<h5 class="mb-0">
<button class="btn btn-link" data-toggle="collapse" data-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
Collapsible Group Item #2
</button>
</h5>
</div>
<div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordionExample">
<div class="card-body">
Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch.
</div>
</div>
</div>
</div>Step 2: Add jQuery Animation Code
$(document).ready(function() {
$('#accordionExample button[data-toggle="collapse"]').on('click', function() {
var $this = $(this);
var $collapse = $this.attr('data-target');
$($collapse).animate({
height: $($collapse).hasClass('show') ? '0' : '100%'
}, 500);
});
});In this example, we’ve added a jQuery script that listens for the click event on the accordion buttons. When a button is clicked, the script animates the height of the corresponding collapse element using the `.animate()` method. The animation duration is set to 500 milliseconds.
Method 3: Anchor Accordion to its Respective Title using JavaScript
If you want to anchor the accordion to its respective title when clicking its button, you can use JavaScript to achieve this functionality.
Step 1: Add the Accordion HTML Markup
<div id="accordionExample">
<div class="card">
<div class="card-header" id="headingOne">

Collapsible Group Item #1
</button>
</h5>
</div>
<div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
<div class="card-body">
Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch.

</div>
<div class="card">
<div class="card-header" id="headingTwo">
<h5 class="mb-0">
<button class="btn btn-link" data-toggle="collapse" data-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">

<div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordionExample">
