The use of drop down menus in WordPress is going to be extremely important because this is going to allow you to distribute your menu tabs efficiently. The way to create drop downs is quite simple. Just go to our menu section in the WordPress control panel and move any menu item that is situated below another item slightly to the right. This is going to lock it as a drop down sub menu of the main menu above it.
You can also create sub menus within the sub menu you created and this makes space management even easier with your WordPress site.
