Load multiple template sections in the same section (ex. inside of shortcode widget)

[neillman]

Hello everyone.
I would like to have a menu (about, contacts, ...) made by me loading diferent template sections without page scroll. They load in the same place without browser loading a new page and the menu/header stays the same withou loading again. Like this page (for example) skylinefilms.tv/

Can some one help me with that?
It would be great.

With best regards
Neillman
