How to keep jQuery UI Accordion collapsed by default ?

Last Updated : 29 Mar, 2022

In this article, we will learn how to keep jQuery UI Accordion collapsed, by default. This can be done by setting the ‘active’ property of jQuery Accordion as false.

Accordion: It is a way to display collapsible content panels for presenting information in a limited amount of space. By clicking on each panel, we can see the content in it, and using the toggling feature, it can collapse the content panel.

The Accordion active option indicates which index of the accordion menu is to be open when the page is accessed. By default, the value is 0, i.e. the first menu panel. When the active option is set to false, it will collapse all the panels.

Please refer to the jQueryUI Accordion active Option article for more detail.

Syntax:

$( "Selector" ).accordion();

Approach:

Firstly, add the jQuery and JQuery UI CDN to the script or download them to your local machine.

<link rel=”stylesheet” href=”http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/themes/dark-hive/jquery-ui.css”> <script src=”http://code.jquery.com/jquery-2.1.3.js”></script> <script src=”http://code.jquery.com/ui/1.11.2/jquery-ui.js”></script>

Create a div in the body for the dialog box and keep id as demoAccordion.

In the demoAccordion div, add 3 div which are going to be panels of the Accordion.

Now, using the jQuery accordion() method, create the Accordion and keep the collapsible property as true.

$("#demoAccordion").accordion({ collapsible: true });

Example: This example describes the jQuery UI Accordion collapse, by specifying its value as true.
