can split panel be used to divide the layout into 3 parts?

Hi,
It is mentioned that split panel is used to divide the layout into 2 parts.but if i want to divide the layout into 3 parts or more what should i use.in what way is split panel used to divide the layout into more parts?what should be used to divide the layout to more parts in (horizontal layout).

You can't have a split panel divided in more than two parts, however, you can have multiple split panels inside each other, thus splitting the view further. So, to have your layout divided into three parts, you need to create one "main" split panel, then put another split panel inside the main split panel.

Anyone can put one example of how we can do that?
