Js achieves linkage between two drop-down boxes
There are two basic methods:
Method 1:
The menu data of menu 1 is provided. When a menu item is clicked, the value of this item is sent to the server, and the server returns new menu data to menu 2.
Method 2:
Menu data is statically stored in js or html elements. When a menu item is clicked, the corresponding menu data is directly sent to menu 2.
 
You can search for "js drop-down menu linkage" in Baidu for the source code.

I have used JS to summarize the folding results. Click the title and a drop-down box will pop up. You can view the detailed answer. Now you can perform fuzzy search.
