Vor einiger Zeit musste das Projekt eine bidirektionale Listenauswahl verwenden. Es stellte sich heraus, dass einige Stile nicht unterstützt wurden, daher musste ich div verwenden, um die folgende Funktion zu simulieren Weitere Funktionen müssen selbst hinzugefügt werden, z. B. in der Liste mehrere Datenspalten anzeigen usw.
