jquerySecondary menu
The example in this article describes how jQuery implements the slide-out secondary menu effect. Share it with everyone for your reference. The details are as follows:
Here we use jQuery to implement the secondary menu code that slides out. When the menu slides out, the mouse is placed on any item of the main menu, and the secondary submenu will slide down. Of course, this code is just a demonstration. Some menus are made casually. After testing, they are compatible with browsers such as IE8, Firefox and Chrome. If you are interested, you can try it yourself.
The screenshot of the running effect is as follows:
The online demo address is as follows:
