My ‘Resume’ could appear here as a ‘sub page‘ to the ‘parent page’ called ‘Autobiography’

In your Dashboard, Select ‘Pages’, Now, either create a new page or select and edit a page you’ve already created.

On the far right hand side of the page editor, you will see a drop down menu called ‘Page attributes’ (see below).

In this case, I’ve chosen Autobiography as the parent page for my Resume page.

Resume now shows as a ‘sub-page’ in the ‘drop down menu’ when you select Autobiography. You can create as many sub-pages as needed (but do be cautious about very long and complex drop down menus… they can become hard to navigate)
