Application Shell 12

Shadcn UI Application Shell Block

ApplicationShell12 is a two-tier sidebar layout with a fixed rail on the left and a collapsible panel that slides in from the right. The rail contains icon buttons for switching between modules, a logo at the top, and user menu at the bottom. The panel displays organization switcher, notification bell, new action button, navigation sections with collapsible configuration area, and utilities. The main content area sits to the right with rounded corners and a neutral background. Mobile view uses a bottom navigation bar and drawer for menu access.

Light neutral color scheme with gray backgrounds and borders. The sidebar rail uses rounded icon buttons with white active states. The panel has a light gray background with rounded left corners. Navigation items use blue accent colors for active states. Smooth animated transitions when the panel expands and collapses, with fade and slide effects. The content area has subtle rounded corners and corner fill elements that appear when the panel is open. Clean, minimal spacing throughout.

Modern application shell with a polished, professional feel. The two-tier sidebar pattern is distinctive and provides efficient navigation without taking up excessive horizontal space. The animated panel transitions add refinement. This is a moderate complexity block that requires navigation module data and organization/user information. The decorative elements are code-driven with CSS transitions and animations rather than relying on images.

Keyboard shortcut support for toggling the sidebar panel. Mobile navigation uses a bottom bar with module icons and a drawer sheet for the full menu. The panel width is fixed at 240px when expanded, with the rail always visible at 64px width.
