The Built-in menu is a useful component for creating a sub-navigation within a content page.
Unlike the Segmented control, this menu has no comparative function and allows users to move seamlessly from one type of content to another, all closely related and located on the same page.
As a sub-level of navigation, it follows the main and tab navigation in the page hierarchy. It keeps users engaged while adding a new level of navigation to the overall content experience.
Work in progress
Please, note that the Built-in menu is a beta component and it will be improved through the following sprints.
