jQuery UI menu collapse() Method
  • Last Updated : 24 Jan, 2021

jQuery UI consists of GUI widgets, visual effects, and themes implemented using jQuery, CSS, and HTML. jQuery UI is great for building UI interfaces for the webpages. jQuery UI menu is a themeable menu that is used with mouse and keyboard interactions for navigating between pages. In this article, we will use the collapse option to collapse the active sub-menu. 

Syntax:

$(".selector").menu( "collapse" );

Approach:

  • First, add jQuery UI scripts needed for your project.

<link href = “https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css” rel = “stylesheet”>

<script src = “https://code.jquery.com/jquery-1.10.2.js”></script>



<script src = “https://code.jquery.com/ui/1.10.4/jquery-ui.js”></script>

Example 1: In this example, we will be using the collapse option for the menu() method.
