In the event that this is not the case,
I will explain with the code. Generally we do like this:
.menu-dropdown {display: none; list-style: none;}
.menu: hover .menu-dropdown {display: block;}
Should I do this with the ul (drop-down menu) outside the ul (menu)?
For example:
.menu-dropdown {display: none; list-style: none;}
.menu: hover .menu-dropdown {display: block;}
As you can see, it did not work there, but how to do it?
