How to make a dropdown menu using div?

Question

HTML

Good day to all.
There is a following menu which I want to implement through html/css. Tell me, is it possible to do this using a div tag, or is there a better option?
On the Internet, all drop-downs are basically implemented through ul and li, which are in nav, but this is not a navigation menu, but a separate button, how would it be more correct to implement it?

Answer 1

It can be done.
In those examples on the web, replace ul/li with div.

Answer 2

You make 2 blocks, for example, and through jquery (show as an option, you can toggle) you show the div you need (in your case, fields and a button). The examples have a lot of options.

Answer 3

So it won't fit?
