Das Beispiel in diesem Artikel beschreibt die JQuery-Implementierung des Navigations-Dropdown-Menüeffektcodes, der für Portalseiten geeignet ist. Teilen Sie es als Referenz mit allen. Die Details lauten wie folgt:

Dies ist ein Web-Navigationsmenü, das mit jQuery CSS geschrieben und implementiert wurde. Der Gesamtstil ist elegant und frisch, einfach und elegant, und es ist ein gutes Menü. Diese Funktion zeichnet sich durch eine gute Kompatibilität und gute Leistung unter Firefox/IE aus. Darüber hinaus wird im Hauptmenü überall dort, wo es sekundäre Untermenüs gibt, ein kleines Dreieckslogo angezeigt, das meiner Meinung nach auch Ihnen gefallen wird.

Der Screenshot des Laufeffekts sieht wie folgt aus:

Die Online-Demo-Adresse lautet wie folgt:
