jQuery accordion is a popular user interface pattern used in web development for creating collapsible content sections. It is typically used to create a list of headers or tabs, which when clicked or hovered upon, expand to reveal content below.
The accordion consists of a container element that holds a list of items, each containing a header and content. The headers are typically clickable, and when clicked, the corresponding content is revealed or hidden. In an accordion, only one item can be expanded at a time, while the others are collapsed.
The jQuery UI library provides an accordion widget that can be easily implemented on a web page. To use it, you first need to include the jQuery and jQuery UI libraries in your HTML code, and then initialize the accordion using jQuery.
