Bootstrap 5 Collapse
Basic Collapsible
Collapsibles are useful when you want to hide and show large amount of content:
Example
<button data-bs-toggle="collapse" data-bs-target="#demo">Collapsible</button>
<div id="demo" class="collapse">
Lorem ipsum dolor text....
</div>

Example Explained
The .collapse class indicates a collapsible element (a <div> in our example);
this is the content that will be shown or hidden with a click of a button.
To control (show/hide) the collapsible content, add the data-bs-toggle="collapse" attribute to an <a> or a <button> element.
Then add the data-bs-target="#id" attribute to
connect the button with the collapsible content (<div id="demo">).
Note: For <a>
elements, you can use the href attribute instead of the data-bs-target
attribute:
Example
<a href="#demo" data-bs-toggle="collapse">Collapsible</a>
<div id="demo" class="collapse">
Lorem ipsum dolor text....
</div>

By default, the collapsible content is hidden. However, you can add the .show class to show the content by default:
Accordion
The following example shows a simple accordion by extending the card component.
Note: Use the data-bs-parent attribute to make
sure that all collapsible elements under the specified parent will be closed when one of the collapsible item is shown.
Example
<div id="accordion">
<div class="card">
<div
class="card-header">
<a class="btn"
data-bs-toggle="collapse" href="#collapseOne">
Collapsible
Group Item #1
</a>
</div>
<div id="collapseOne" class="collapse show"
data-bs-parent="#accordion">
<div class="card-body">
Lorem
ipsum..
</div>
</div>
</div>
<div class="card">
<div
class="card-header">
<a class="collapsed

data-bs-toggle="collapse" href="#collapseTwo">
Collapsible
Group Item #2

</div>
