Sidebar
A responsive, composable sidebar system with provider-managed state, desktop collapse modes, and a mobile sheet layout. It includes primitives for headers, groups, navigation menus, nested links, actions, badges, and loading skeletons.
Installed with shadcn add · 3 workarounds (recipe written by a coding agent) · theme from the install docs
- applied the registry's theme (tokens, fonts and CSS from the registry preview settings)
- added compat file hooks/use-mobile.ts
- redirected import @/hooks/use-mobile to a compat file
Installation
pnpm dlx shadcn@latest add https://neobrutalism.com/r/sidebar.json
Usage
usage.tsx
import { Sidebar, SidebarContent, SidebarInset, SidebarMenu, SidebarMenuButton, SidebarMenuItem, SidebarProvider, SidebarTrigger,} from "@/components/ui/sidebar"export function AppSidebar() { return ( <SidebarProvider> <Sidebar collapsible="icon"> <SidebarContent> <SidebarMenu> <SidebarMenuItem> <SidebarMenuButton isActive>Dashboard</SidebarMenuButton> </SidebarMenuItem> </SidebarMenu> </SidebarContent> </Sidebar> <SidebarInset> <SidebarTrigger /> <main>Page content</main> </SidebarInset> </SidebarProvider> )}- Build application navigation that needs expandable or icon-only desktop states and a sheet-based mobile layout.
- Organize links into labeled navigation groups with active states, secondary actions, badges, or nested links.
- Pair a sidebar with a main content region that should respond to an inset sidebar variant.
- Use the provider when sidebar state should be controlled externally, persisted in a cookie, or toggled by the built-in keyboard shortcut.
API reference
PropTypeDefaultDescription
SidebarProviderReact.ComponentProps<"div"> & { defaultOpen?: boolean; open?: boolean; onOpenChange?: (open: boolean) => void }—Provides sidebar state and renders the wrapper. `defaultOpen` defaults to `true`; `open` and `onOpenChange` enable controlled state. Writes the open state to the `sidebar_state` cookie for seven days. Toggles with Ctrl+B or Cmd+B.
SidebarReact.ComponentProps<"div"> & { side?: "left" | "right"; variant?: "sidebar" | "floating" | "inset"; collapsible?: "offcanvas" | "icon" | "none" }—`side` defaults to `"left"`, `variant` to `"sidebar"`, and `collapsible` to `"offcanvas"`. Must be rendered inside `SidebarProvider`. On mobile, it renders through the sheet components; desktop collapse behavior is controlled by the provider.
SidebarTriggerReact.ComponentProps<typeof Button>—Renders the shared Button with ghost styling and the `icon-sm` size by default. Its click handler calls the supplied `onClick`, then toggles the sidebar.
SidebarRailReact.ComponentProps<"button">—A sidebar-edge button that toggles the sidebar. Its source sets `aria-label` and `title` to `Toggle Sidebar` and sets `tabIndex` to `-1`.
SidebarInsetReact.ComponentProps<"main">—Renders the main content region and applies inset-variant layout styling at the `md` breakpoint.
SidebarInputReact.ComponentProps<typeof Input>—Renders the shared Input with sidebar input data attributes and default `h-8 w-full bg-background shadow-none` styling.
SidebarHeaderReact.ComponentProps<"div">—A div-based header region with default vertical layout, gap, and padding.
SidebarFooterReact.ComponentProps<"div">—A div-based footer region with default vertical layout, gap, and padding.
SidebarSeparatorReact.ComponentProps<typeof Separator>—Renders the shared Separator with sidebar-border coloring and horizontal margins.

SidebarGroupReact.ComponentProps<"div">—A div-based container for a navigation group.
SidebarGroupLabeluseRender.ComponentProps<"div"> & React.ComponentProps<"div">—A renderable group label with default div rendering. Its label styling is hidden in icon-collapsed desktop state.
SidebarGroupActionuseRender.ComponentProps<"button"> & React.ComponentProps<"button">—A renderable button positioned as an action within a group.
SidebarGroupContentReact.ComponentProps<"div">—A div-based content region for a sidebar group.
SidebarMenuReact.ComponentProps<"ul">—A list container for sidebar menu items.
SidebarMenuItemReact.ComponentProps<"li">—A list item container for menu buttons, actions, badges, or nested menus.
SidebarMenuButtonuseRender.ComponentProps<"button"> & React.ComponentProps<"button"> & { isActive?: boolean; tooltip?: string | React.ComponentProps<typeof TooltipContent> } & VariantProps<typeof sidebarMenuButtonVariants>—`isActive` defaults to `false`; `variant` and `size` default to `"default"`. Variants are `default` and `outline`; sizes are `default`, `sm`, and `lg`. `render` is provided through the useRender component props. `tooltip` accepts a string or TooltipContent props; tooltips are hidden unless the desktop sidebar is collapsed.
SidebarMenuActionuseRender.ComponentProps<"button"> & React.ComponentProps<"button"> & { showOnHover?: boolean }—A renderable menu-item action button. `showOnHover` defaults to `false` and applies hover/focus visibility styling when enabled.
SidebarMenuBadgeReact.ComponentProps<"div">—A div-based badge positioned within a menu item; it is hidden in icon-collapsed desktop state.
SidebarMenuSkeletonReact.ComponentProps<"div"> & { showIcon?: boolean }—`showIcon` defaults to `false`. Renders skeleton text with a per-instance random width between 50% and 89%, and optionally an icon placeholder.
SidebarMenuSubReact.ComponentProps<"ul">—A nested menu list with a leading border; hidden in icon-collapsed desktop state.

useSidebarNo props; returns { state: "expanded" | "collapsed"; open: boolean; setOpen: (open: boolean) => void; openMobile: boolean; setOpenMobile: (open: boolean) => void; isMobile: boolean; toggleSidebar: () => void }—Reads sidebar state from SidebarProvider and throws an error when called outside the provider.
Accessibility
- Use SidebarProvider around Sidebar and any components that call useSidebar; the hook throws if used outside the provider.
- SidebarTrigger includes screen-reader-only text, `Toggle Sidebar`.
- SidebarRail has an accessible label and title, but its `tabIndex` is set to `-1` in the source, so it is removed from sequential keyboard navigation.
- SidebarMenuButton supports native button props and state attributes, including `disabled`; use `isActive` to expose its active state through the rendered state attributes and styles.
- SidebarMenuSubButton renders as an anchor by default; provide appropriate link attributes such as `href` for navigation.
- The mobile sidebar uses the sheet's title and description, visually hidden with `sr-only`.
