Glass Sidebar is a collapsible

Glass Sidebar is a collapsible glassmorphism rail that animates between an icon-only and a fully-labeled state with a single spring-driven transition.

Each row stays touch-friendly in both modes, and the labels fade in with a slight stagger so the expansion feels intentional.

The glass surface uses backdrop-filter, so it always picks up the background color of the app beneath. It is the default left rail for SaaS dashboards, admin panels, and any web app where you want a clean primary navigation that gets out of the way on demand.
