Tales incorporates two menu locations, the Primary Menu and the Footer Menu. See the WordPress Menu User Guide for a full step-by-step guide to creating and managing menus.
The Primary Menu is opened via the navigation icon in the website’s header (top-right corner). This menu slides into view displaying top-level items.
Second-level items are displayed within pages that share the same top-level parent. For example, the “Documentation” section you’re reading now includes this page, “Menus”, as a child item.
The Footer Menu displays a single level and sits at the end of every page.
