Hi Pascale,
Just so I undertand your question, the new page that you have is not part of the menu and hence you want to remove navigation when user is viewing this page, right?
This is totally achievable. There are different ways of doing this:
- If you are using a different template for these pages, you can remove navigation from the structure of the template. That way it will not be there in any of the page created from this template.
- If you are using same template for these pages as well, you could add a authorable field in page property, to allow authors to disable navigation from the page. You could then use this property in navigation component to hide it as needed.
Let me know if this helps! 🙂
Cheers!
