js implements the secondary menu effect of sliding out horizontally to the right

The example in this article describes the js implementation of the secondary menu effect that slides out horizontally to the right. Share it with everyone for your reference. The details are as follows:

This is a horizontally sliding out secondary menu on a web page. The menu is arranged vertically, but the secondary submenu items slide out horizontally to the right. A JS packaging library file is introduced. In terms of compatibility of this menu It's done pretty well, but I think some of the codes in the menu are difficult to modify. If you're interested, check it out for yourself.

The screenshot of the running effect is as follows:

The online demo address is as follows:
