To style the elements, CSS is the way to go. It is specifically designed for that purpose.
When it comes to deciding when to display or hide them, JavaScript is necessary unless you want:
:hover will make it disappear before you can navigate back inside Personally, I would prefer to avoid using drop-down menus in most cases.
My suggestion is to utilize CSS whenever possible in order to avoid potential issues with JavaScript being disabled or other accessibility concerns. Given that site navigation menus are crucial for user experience, it's essential that they are accessible to all segments of users. Check out this resource for pure CSS options, or search online for tutorials on creating pure CSS menus. You may also find this example of a jQuery & CSS menu interesting here.
It is possible to create them using only CSS. See this example of a Pure CSS hover list.
Users often disable JavaScript for security reasons, which can make creating drop-down menus complicated. Pure JavaScript menus may not work on browsers that don't support it, like text-only browsers. However, CSS-based menus are always accessible, even if JavaScript is disabled – these browsers will simply display a list instead.
By using this method, adding a menu to a webpage becomes as simple as generating an unordered list of links with sub-menus nested within, and applying the appropriate style-sheet.
