Ich verwende eine Menubar mit JS auf unserer Homepage --> www.seitelschlag.at
das funktioniert eigentlich soweit. nur sind mir 2 Kleinigkeiten aufgefallen die meiner Meinung nach mit neuen Browser wie Edge oder Chrome zusammen hängen.
1. unter Chrome auf Android muss man die nach unten ausklappbaren Buttons 2 mal abwechselnd anklicken damit sie funktionieren
2. weiters funktioniert das ausklappen nicht wenn man mit dem Tabulator drüber geht. wird sicher selten verwendet aber vielleicht lässt es sich fixen
da ich mich mit JS wenig bis gar nicht beschäftigt habe hier meine bitte um Unterstützung
