Lading page to different pages

Hi,

My site : vooruitstrevendeliberalevolkspartij.ga is now like one page with all the subpages on it.
I want my homepage to just be the first page, but i don’t get how to do this.
I now have like:
Home
Partijbestuur
Standpunten

But all this pages are shown on the homepage and you can just scroll down to them.
I want to change this so you can only acces this pages by clicking on the thingy in the menu.

Can anyone help me with this?

Are you using zyro builder?
