bs-navbar is the Angular wrapper around the framework-agnostic <mp-navbar> web component. The bar chrome, the responsive collapse (a pure-CSS state machine), the hamburger toggle and the theme-aware styling all live in the WC. Mark the brand with bs-navbar-brand, group entries in a bs-navbar-nav (align="end" pushes a group to the far edge), and use bs-navbar-item for every entry — directly in a group as a nav-link, or inside a bs-navbar-dropdown as a menu item; the same element adapts to where it is authored. A dropdown's trigger is the element marked bsNavbarDropdownLabel — any HTML (give an icon-only label an aria-label). Toggling the collapse fires (expandedchange).
