## Overview

The **Accordion** component is a collapsible menu. Clicking the header area — consisting of an icon and a heading — expands the content to reveal additional information. It is an interactive navigation element designed to present extensive content in a space-saving manner.

Accordions are used whenever content associated with a thematic heading needs to be shown or hidden. They allow more detailed information for a heading than would normally be practical, leaving it to the users to decide whether to view that information.
