Stop Auto Adding Page to Menu

Hello.

Thanks for posting your question regarding disabling the menu from automatically adding newly published pages. To do this, you will need to navigate to Customize > Menus, then click on the menu that is adding the new pages automatically. Scroll down to the Menu Options section. You should see the checkbox for “Automatically add new top-level pages to this menu“, uncheck that box to disable this behavior.

Best Regards,

Carlos D
