I'm trying to add three top links that are to work as parent of the main navigation. The three top-links are static but the main and sub menu is not. Each top-link has its own main navigation.

Here is how the navigation tree looks like:

The static links are not supposed to be changed.

Please note that Top-link1 is the HomePage

I want the pathway to be like this for example:

"Top-link2/Menu3/submenu3" or

"Top-link3/menu 2/submenu5"

My question is: How should the structure be on the content? Should the top-links be included inside the HomePage or outside the HomePage? What should I do to achieve this?
