Subpages are pages that appear below the main pages in your site navigation. They typically appear as drop-down menu.
To create a subpage
Open the Pages menu on the Left Sidebar.
Ensure the subpage is position below the parent page (you can do so by selecting the page and dragging it up or down).
Or, create a new page that you would like to be a subpage, or child page to your parent page and position it.
Click on the Page (new or existing) to select it and and drag it to right.
You will see the subpage icon and click save.
A subpage has the same editing functionality as a parent page, it can be renamed, duplicated, hidden, published, unpublished and deleted.
Tip: You can edit the Pages settings such as the font size, colour, drop down option etc... from the right sidebar.
