I. Introduction
A. Overview of the Collapse Component
The Collapse Component in Bootstrap 5 allows you to expand or collapse sections of your web page, making it an essential tool for creating dynamic and interactive user interfaces. By using this component, developers can condense information in a way that improves user experience and improves the aesthetics of their websites.

- Enhanced User Experience: Users can navigate content easily without feeling overwhelmed.
- Improved Responsiveness: Collapsible components adapt well to different screen sizes, especially on mobile devices.
II. How to Create a Collapse Component
A. Basic Structure
To understand how to create a Collapse Component, let’s look at its basic HTML structure:
<div class="accordion" id="accordionExample">
<div class="accordion-item">
<h2 class="accordion-header">
<button class="accordion-button collapsed" type="button" data-bs-toggle="collapse"
data-bs-target="#collapseOne" aria-expanded="false" aria-controls="collapseOne">
Collapsible Item #1
</button>
</h2>
<div id="collapseOne" class="accordion-collapse collapse" aria-labelledby="headingOne"
data-bs-parent="#accordionExample">
<div class="accordion-body">
This is the content of the first collapsible item.
</div>
</div>
</div>
</div>B. Implementing Collapse with Examples
Now, let’s implement the Collapse Component with practical examples:
<button class="btn btn-primary" type="button" data-bs-toggle="collapse"
data-bs-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
Toggle Content
</button>
<div class="collapse" id="collapseExample">
<div class="card card-body">
This content is hidden until you toggle the button!
</div>
</div>III. Collapse Options
A. Data Attributes
Bootstrap 5 allows you to create collapses via data attributes. Here are some of the key attributes:
| Attribute | Description |
|---|---|
| data-bs-toggle | Toggles the collapse |
| data-bs-target | Specifies the target element to collapse |
| aria-expanded | Indicates whether the element is expanded or not |
B. Method: collapse()
The collapse() method provides another way to control the collapse programmatically. Here’s how you can use this method:
var myCollapse = document.getElementById('collapseExample')
var bsCollapse = new bootstrap.Collapse(myCollapse, {
toggle: true
})C. Events
Bootstrap 5 also supports events related to the Collapse Component, such as:
| Event | Description |
|---|---|
| show.bs.collapse | Triggered just before the collapse occurs |
| shown.bs.collapse | Triggered after a collapse has been made visible |
| hide.bs.collapse | Triggered just before the collapse begins to hide |
| hidden.bs.collapse | Triggered after a collapse has been hidden |
IV. Examples
A. Collapsible Item
Let’s explore a simple example of a collapsible item:
<div class="container">
<h2>Collapsible Item Example</h2>
<button class="btn btn-secondary" type="button" data-bs-toggle="collapse"
data-bs-target="#demoCollapse" aria-expanded="false" aria-controls="demoCollapse">
Click to Expand
</button>
<div class="collapse" id="demoCollapse">
<div class="card card-body">
Here is some great content that you can collapse!
</div>
</div>
</div>B. Accordion Example

<div class="accordion" id="accordionExample">
<div class="accordion-item">
<h2 class="accordion-header">
<button class="accordion-button" type="button" data-bs-toggle="collapse"
data-bs-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">

<div id="collapseOne" class="accordion-collapse collapse show"
aria-labelledby="headingOne" data-bs-parent="#accordionExample">
<div class="accordion-body">
This is the first item's accordion body.
</div>
</div>
<div class="accordion-item">
<h2 class="accordion-header">
<button class="accordion-button collapsed" type="button" data-bs-toggle="collapse"
data-bs-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
