The first thing to do is create the HTML structure for our drop down menu. For this purpose the DeveloperDrive Team will use the HTML5 element, then add the primary navigation links in a simple unordered list. Now that they have their basis layout it is time for use to start creating the sub-menus. For the first sets of sub-menus add the “Categories” and the “Most Popular”. Now that you have created the first sub-menus it is time for you to create a sub-menu within the sub-menu. When you are finished with the basic menu it is time to add the styling with CSS. The first thing they want to do is to hide the sub menus, they will do this by telling the code to hide any UL’s that are already inside a UL by using declaration.
