This is a custom block plugin for the Kirby CMS. It is used to add a custom accordion block that uses semantic HTML. Shipping without any CSS requirements, it is unopinionated but easy to style if you are so inclined.
Requires a computer running an operating system. The computer must have some memory and ideally some kind of long-term storage. An input device as well as some form of output device is recommended.
An accordion is used to show (and hide) HTML content. In the case of this plugin, this can be one or more collapsable elements.
They are sometimes also known as a disclosure widget or a twistie.
