Here’s how you can create a horizontal navigation bar with drop-down feature using CSS. The limitation of this code is that it can only handle 1 level of sub menu. So if you intend you create more levels, you have to add to the code.
CSS properties will vary depending on your existing layout and styles, but basically the horizontal drop-down menu works by converting an unordered vertical list into a horizontal one, and hiding any sub list from sight until the parent is hovered by the mouse.
