Hi,
Is there a way when creating a new page, to have a new menu automatically created in the bar menu ?
Is there a way to chose if the new menu of our new page can be change in new menu or sub menu of a already existing menu ?

Hi and welcome.

Yes, we can certainly do so.
It has been discussed in detail here :http://www.couchcms.com/docs/concepts/nested-pages-aka-menu-maker.html

Do let me know if you require help with something.
Thanks.
