Akkordeon
Erstellen Sie vertikal kollabierende Akkordeons in Kombination mit unserem Collapse-JavaScript-Plugin.
Wie es funktioniert
Das Akkordeon verwendet intern den Zusammenbruch , um es zusammenklappbar zu machen. Um ein erweitertes Akkordeon zu rendern, fügen Sie die .open
Klasse in der .accordion
.
