Hallo an Alle!
Habe ein tolles JavaScript Menü gefunden und in meine Homepage eingebaut.
Sehr viele Links sind auf meiner Site und mich stört, dass der User das Menü voll ausklappen kann.
Das Ende der Site ist dann schnell erreicht und ab da ist der Aufbau leider sehr langsam.
Ich würde mir wünschen das immer nur ein Menüpunkt mit seinen Unterpunkten geöffnet werden kann.
Klickt der User auf einen weiteren sollte sich der aktive wieder schließen.
Vielleicht kann mir jemand weiterhelfen, habe mit Java noch kaum Erfahrung.
Vielen Dank im Vorraus! Chriz
