Beyond groups, galleries, and collections there are many built-in pages that make up your website. You can make all your pages more easily accessible by adding links to them in your site menu.
Most site menus are kept to five or seven links. You may also choose to include dropdown menus with many more links. Links may access groups, galleries and collections, built-in pages as well as custom pages you have created, links to uploaded PDF files, and external links to sites not part of your Zenfolio account.
This video walks you through the process of adding these links to the site menu.
