What is Drop-down Menu?

The menus on the websites that open when you click on them or when you hover the cursor with the mouse are called Drop-down or Drop-Down 
Menus. Drop-down menus are especially used on websites with a large number of menu items or categories to include them all without taking up 
too much space.

What Happens If An Item Is Clicked In The Pop-up Menu?
When you click on any item in the drop-down menu, you will be directed to the clicked page. For example, let's say Male is the main category. Polo 
and Tshirt also get dropdown menus. When you click on one of these created menus, you reach that page content. The page you will reach can be a 
sales page or a content page.

Drop-down menus can be horizontal or vertical. Adding too many submenus in vertical drop-down menus may not look good as an image. In these 
cases, horizontal drop-down menus should be preferred.
