The example in this article describes how to implement a multi-level drop-down menu with arrow logo using JavaScript. Share it with everyone for your reference. The details are as follows:
This is a JS menu that supports multi-level display. Move the mouse to the menu item with a small triangle to pull out the second-level submenu item. A mark will be displayed above the main menu to guide the current position. The menu code uses a JS class, which can be downloaded according to the code address. This menu has not been tested online. You may need to modify the code to use it in your own website.
The screenshot of the running effect is as follows:
The online demo address is as follows:
