Pure jquery to implement drop-down menu effect (code example)

The example in this article describes how jquery can display underline and drop-down menu effects when the mouse passes over it. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

What is introduced here is a website slide-down navigation menu with a black and red gradient. It is a slide-down navigation menu implemented based on jquery. When the mouse passes the main menu, the slide-down menu will automatically follow where it goes. If the menu If there are two levels of submenus, the drop-down menu will also be displayed with a gradient effect. The menu operation is very sensitive and uses a custom encapsulated plug-in SuperSlide.2.1.js. Please download this JS plug-in when using it.

A screenshot of the running effect is as follows:
