The example in this article describes the js implementation of the Microsoft official website navigation drop-down menu effect with good compatibility. Share it with everyone for your reference. The details are as follows:

This is a Microsoft official website navigation menu, which is compatible with drop-down menus and has Microsoft official website navigation effects. There is no animation effect under IE6. By the way, IE6 effects are also added, making it compatible with IE6. Microsoft's official website is now in use, which I think is very good.

The screenshot of the running effect is as follows:

The online demo address is as follows:

The specific code is as follows:
