How to create simple accordion using jQuery, HTML & CSS

In this simple post I am going to share and explaing the simple jQuery code to create a simple accordion.

Though, accordion is available in jQuery UI and Bootstrap but still if you are not using jQuery UI and Bootstrap and want to create a simple accordion then you can achieve the same by following code.

First,I have created a HTML code like below.

<div class="accordion">
   <a href="#" >Anchor 1</a>
</div>
<div class="accordion-body">
   This is the div to show 1
   <p>Lorem Ipsum.....</p>
</div>
<div class="accordion">
   <a  href="#" >Anchor 2</a>
</div>
<div class="accordion-body">
   This is the div to show 2
   <p>Lorem Ipsum...</p>
</div>
<div class="accordion">
   <a href="#" >Anchor 3</a>
</div>
<div class="accordion-body">
   This is the div to show 3
   <p>Lorem Ipsum....</p>
</div>
<div class="accordion">
   <a href="#" >Anchor 4</a>
</div>
<div class="accordion-body">
   This is the div to show 4
   <p>Lorem Ipsum....</p>
</div>

Then I also added some basic CSS code to make our accordion look better.

.accordion {
background-color:#ddd;
background-image:linear-gradient(#ddd,#ededed);
cursor:pointer;
padding:15px;
}

.accordion a {
text-decoration:none;
color:#000;
}

.accordion-body {
display:none;
border:1px solid #ddd;
border-top:none;
padding:10px;
}

Now its time to convert this basic div structure in working accordion. For that, I have added small jQuery code like below.

$(".accordion").on("click",function()
{ 
   var accordianBody = $(this).next();                     
   $(".accordion-body").not(accordianBody).slideUp("slow"); 
   $(accordianBody).slideToggle();

});

That's it. Our "Accordion" is ready which you can see live in below jsFiddle.

Now lets understand the jQuery code. HTML and CSS is very basic which you can understand easily.

There is a div having class "accordion" and its body in div which has class named "accordion-body". In jQuery we have handled a click event for "accordion" div. 

In click event, we first created an object of its related div i.e. "accordion-body" by using below line.

var accordianBody = $(this).next();

Then, I have set all accordion body divs in hidden state by using below line of code. In this I have used .not() function which restricts the behaviour of hiding and showing the accordion body if user clicks on accordion div more than once.

$(".accordion-body").not(accordianBody).slideUp("slow"); 

Now using below line of code I have toggled the state of accordion body.

$(accordianBody).slideToggle();
