The "Navigation" element is a very useful tool that offers the possibility to add links to already created pages. This can save you a lot of work when creating new pages because you don't have to manually link to them.
You have two main options:
1. Display all pages that meet your criteria. You have the option to hide the selected ones.
2. Display only the pages you select.
Click on the name of a selected page to make it visible or hide it. If it's hidden, you'll see a scratched-out eye icon.
You can also display a link to the home page.
