Bonzai Intranet navigation
Bonzai Intranet provides various types of navigation functionality that allows an organization to define a hierarchy within that can be visible including the top main mega-menu, header links and footer links.
Navigation is driven by SharePoint Term Sets that allow users to create a hierarchy, define links to internal SharePoint content or external urls, and define a name for each link.
Bonzai Intranet also uses a number different performance optimizations for navigation such as local storage so that navigation appears to be instant to users.
