Prevent menu from displaying

I need to publish some pages on my website for a month or 2. This will be accessed from another website. I don’t want the full menu of the rest of the site to be accessed. Is there a way to do this. Fairly new user
Thank you

In Settings on the right hand side in Edit mode you can mark any pages you want to hide as Draft and then they won’t be displayed in the menu. They’ll still be published but visitors won’t see them unless they know the specific URL for each page.
