I have located information through the forum on how to allow for second and third tier pages to appear as a sub menu item and drop down from the main menu button. However, when you get to the third tier these drop to the side.
So my navigation bar is horizontal. The first sub menu item is fine and drops down underneath and I can customize it to appear the same but when I add the third it goes to the side. What I wanted to create was a drop down menu that drops down vertically giving two or three options under the main menu.
