ns-ui
Drill-down navigation where every pushed level compresses into a slim clickable book spine instead of vanishing behind a back button, so the whole navigation history stands on a shelf beside you.
Use when full-page drill-down navigation through a record hierarchy where the levels behind you should stay on screen and clickable as compressed book spines instead of hiding behind a back button; pick menu-nested-trays instead when the nested content is genuinely a menu with menuitem semantics rather than real page content per level, or breadcrumb-overflow-menu when the trail is a text path above otherwise static content rather than the navigation mechanism itself.
