I am guessing this is a NavigationSplitView and the menu is in the sidebar closure. But I'm not quite sure how to reproduce this style of menu. Along with the collapsing breadcrumb for back button. I would have thought this would be out of the box?

With the paradeTemplate I have a highlight event bound to the individual listItemLockup elements however it isn't clear to me how I am supposed to side load in new relatedContent images into the imgDeck tag.
