I have a problem with part of the html and css code
I am working on a menu that has children. Unfortunately, this child cannot be opened by holding the mouse over it. I have put the html & css code inside the website site so that friends can give a proper guide.

The below code was missing, where we make the dropdown ul tag visible on hover!
#mainNavigation nav.desktop ul li.dropdown:hover ul {
visibility: visible;
opacity:1;
}
