Element for folding in and out page or text areas.

The accordeon content object is a container object, thus it may contain different other content object (but not containers). I may be defined as open or closed when entering the web page. 

Planned but not yet implmented: 

With an auto-open functionality at the end of each accordeon element a next-step button is displayed that opens the next accordeon element on the page and closes the current one at the same time. This feature would be very helpful to make long forms (like membership applications) look less daunting. 

This feature does not require an extension.

This feature was already used in this(these) version(s):
