Checkout page layout (itemid)

Hello,
How to select the layout of the "checkout" page ?
On my site, the checkout page is displayed as on the home page. Now I would like this layout to be like on another menu link (select another itemid link ?).

How can I edit this page ?

Thanks,
Seb

Resolved, i found it in the menu item.

Hello Sebastien,

That's fine. For other customers, this is the documentation: eshopdocs.joomservices.com/getting-start...owsing-the-front-end
