Sidebar

A composable, themeable and customizable sidebar component.

Sidebars are one of the most complex components to build. They are central to any application and often contain a lot of moving parts.

I don't like building sidebars. So I built 30+ of them. All kinds of configurations. Then I extracted the core components into sidebar.tsx.

We now have a solid foundation to build on top of. Composable. Themeable. Customizable.

Browse the Blocks Library.

Installation

Run the following command to install `sidebar.tsx`

npx shadcn@latest add sidebar

Add the following colors to your CSS file

The command above should install the colors for you. If not, copy and paste the following in your CSS file.

We'll go over the colors later in the theming section.

app/globals.css

  :root {
    --sidebar-background: 0 0% 98%;
    --sidebar-foreground: 240 5.3% 26.1%;

Structure

A Sidebar component is composed of the following parts:

SidebarProvider - Handles collapsible state.
Sidebar - The sidebar container.
SidebarHeader and SidebarFooter - Sticky at the top and bottom of the sidebar.
SidebarContent - Scrollable content.
SidebarGroup - Section within the SidebarContent.
SidebarTrigger - Trigger for the Sidebar.

Usage

app/layout.tsx

import { SidebarProvider, SidebarTrigger } from "@/components/ui/sidebar"
import { AppSidebar } from "@/components/app-sidebar"
 
export default function Layout({ children }: { children: React.ReactNode }) {
  return (
    <SidebarProvider>
      <AppSidebar />
      <main>
        <SidebarTrigger />
        {children}
      </main>
    </SidebarProvider>
  )
}

components/app-sidebar.tsx

import {
  Sidebar,
  SidebarContent,
  SidebarFooter,
  SidebarGroup,
  SidebarHeader,
} from "@/components/ui/sidebar"
 
export function AppSidebar() {
  return (
    <Sidebar>
      <SidebarHeader />
      <SidebarContent>
        <SidebarGroup />
        <SidebarGroup />
      </SidebarContent>
      <SidebarFooter />
    </Sidebar>
  )
}

Your First Sidebar

Let's start with the most basic sidebar. A collapsible sidebar with a menu.

Add a `SidebarProvider` and `SidebarTrigger` at the root of your application.

app/layout.tsx

import { SidebarProvider, SidebarTrigger } from "@/components/ui/sidebar"
import { AppSidebar } from "@/components/app-sidebar"
 
export default function Layout({ children }: { children: React.ReactNode }) {
  return (
    <SidebarProvider>
      <AppSidebar />
      <main>
        <SidebarTrigger />
        {children}
      </main>
    </SidebarProvider>
  )
}

Create a new sidebar component at `components/app-sidebar.tsx`.

components/app-sidebar.tsx

import { Sidebar, SidebarContent } from "@/components/ui/sidebar"
 
export function AppSidebar() {
  return (
    <Sidebar>
      <SidebarContent />
    </Sidebar>
  )
}

Now, let's add a `SidebarMenu` to the sidebar.

We'll use the SidebarMenu component in a SidebarGroup.

components/app-sidebar.tsx

import { Calendar, Home, Inbox, Search, Settings } from "lucide-react"
 
import {
  Sidebar,
  SidebarContent,
  SidebarGroup,
  SidebarGroupContent,
  SidebarGroupLabel,
  SidebarMenu,
  SidebarMenuButton,
  SidebarMenuItem,
} from "@/components/ui/sidebar"
 
// Menu items.
const items = [
  {
    title: "Home",
    url: "#",
    icon: Home,
  },
  {
    title: "Inbox",
    url: "#",
    icon: Inbox,
  },
  {
    title: "Calendar",
    url: "#",
    icon: Calendar,
  },
  {
    title: "Search",
    url: "#",
    icon: Search,
  },
  {
    title: "Settings",
    url: "#",
    icon: Settings,
  },
]
 
export function AppSidebar() {
  return (
    <Sidebar>
      <SidebarContent>
        <SidebarGroup>
          <SidebarGroupLabel>Application</SidebarGroupLabel>
          <SidebarGroupContent>
            <SidebarMenu>
              {items.map((item) => (
                <SidebarMenuItem key={item.title}>
                  <SidebarMenuButton asChild>
                    <a href={item.url}>
                      <item.icon />
                      <span>{item.title}</span>
                    </a>
                  </SidebarMenuButton>
                </SidebarMenuItem>
              ))}
            </SidebarMenu>
          </SidebarGroupContent>
        </SidebarGroup>
      </SidebarContent>
    </Sidebar>
  )
}

You've created your first sidebar.

Components

The components in sidebar.tsx are built to be composable i.e you build your sidebar by putting the provided components together. They also compose well with other shadcn/ui components such as DropdownMenu, Collapsible or Dialog etc.

If you need to change the code in sidebar.tsx, you are encouraged to do so. The code is yours. Use sidebar.tsx as a starting point and build your own.

In the next sections, we'll go over each component and how to use them.

SidebarProvider

The SidebarProvider component is used to provide the sidebar context to the Sidebar component. You should always wrap your application in a SidebarProvider component.

Props

Name	Type	Description
`defaultOpen`	`boolean`	Default open state of the sidebar.
`open`	`boolean`	Open state of the sidebar (controlled).
`onOpenChange`	`(open: boolean) => void`	Sets open state of the sidebar (controlled).

Width

If you have a single sidebar in your application, you can use the SIDEBAR_WIDTH and SIDEBAR_WIDTH_MOBILE variables in sidebar.tsx to set the width of the sidebar.

components/ui/sidebar.tsx

const SIDEBAR_WIDTH = "16rem"
const SIDEBAR_WIDTH_MOBILE = "18rem"

For multiple sidebars in your application, you can use the style prop to set the width of the sidebar.

To set the width of the sidebar, you can use the --sidebar-width and --sidebar-width-mobile CSS variables in the style prop.

components/ui/sidebar.tsx

<SidebarProvider
  style={{
    "--sidebar-width": "20rem",
    "--sidebar-width-mobile": "20rem",
  }}
>
  <Sidebar />
</SidebarProvider>

This will handle the width of the sidebar but also the layout spacing.

Keyboard Shortcut

The SIDEBAR_KEYBOARD_SHORTCUT variable is used to set the keyboard shortcut used to open and close the sidebar.

To trigger the sidebar, you use the cmd+b keyboard shortcut on Mac and ctrl+b on Windows.

You can change the keyboard shortcut by updating the SIDEBAR_KEYBOARD_SHORTCUT variable.

components/ui/sidebar.tsx

const SIDEBAR_KEYBOARD_SHORTCUT = "b"

Persisted State

The SidebarProvider supports persisting the sidebar state across page reloads and server-side rendering. It uses cookies to store the current state of the sidebar. When the sidebar state changes, a default cookie named sidebar:state is set with the current open/closed state. This cookie is then read on subsequent page loads to restore the sidebar state.

To persist sidebar state in Next.js, set up your SidebarProvider in app/layout.tsx like this:

app/layout.tsx

import { cookies } from "next/headers"
 
import { SidebarProvider, SidebarTrigger } from "@/components/ui/sidebar"
import { AppSidebar } from "@/components/app-sidebar"
 
export async function Layout({ children }: { children: React.ReactNode }) {
  const cookieStore = await cookies()
  const defaultOpen = cookieStore.get("sidebar:state")?.value === "true"
 
  return (
    <SidebarProvider defaultOpen={defaultOpen}>
      <AppSidebar />
      <main>
        <SidebarTrigger />
        {children}
      </main>
    </SidebarProvider>
  )
}

You can change the name of the cookie by updating the SIDEBAR_COOKIE_NAME variable in sidebar.tsx.

components/ui/sidebar.tsx

const SIDEBAR_COOKIE_NAME = "sidebar:state"

<SidebarProvider>
  <Sidebar variant="inset" />
  <SidebarInset>
    <main>{children}</main>
  </SidebarInset>
</SidebarProvider>

      <Sidebar>
        <SidebarHeader />
        <SidebarContent />
        <SidebarFooter>
          <SidebarMenu>
            <SidebarMenuItem>
              <DropdownMenu>
                <DropdownMenuTrigger asChild>
                  <SidebarMenuButton>

          </SidebarMenu>
        </SidebarFooter>
      </Sidebar>
    </SidebarProvider>
  )
}

SidebarContent

The SidebarContent component is used to wrap the content of the sidebar. This is where you add your SidebarGroup components. It is scrollable.

import { Sidebar, SidebarContent } from "@/components/ui/sidebar"
 
export function AppSidebar() {
  return (
    <Sidebar>
      <SidebarContent>
        <SidebarGroup />
        <SidebarGroup />
      </SidebarContent>
    </Sidebar>
  )
}

SidebarGroup

Use the SidebarGroup component to create a section within the sidebar.

A SidebarGroup has a SidebarGroupLabel, a SidebarGroupContent and an optional SidebarGroupAction.

import { Sidebar, SidebarContent, SidebarGroup } from "@/components/ui/sidebar"
 
export function AppSidebar() {
  return (
    <Sidebar>
      <SidebarContent>
        <SidebarGroup>
          <SidebarGroupLabel>Application</SidebarGroupLabel>
          <SidebarGroupAction>
            <Plus /> <span className="sr-only">Add Project</span>
          </SidebarGroupAction>
          <SidebarGroupContent></SidebarGroupContent>
        </SidebarGroup>
      </SidebarContent>
    </Sidebar>
  )
}

Collapsible SidebarGroup

To make a SidebarGroup collapsible, wrap it in a Collapsible.

demo-sidebar-group-collapsible — A collapsible sidebar group.

export function AppSidebar() {
  return (
    <Collapsible defaultOpen className="group/collapsible">
      <SidebarGroup>
        <SidebarGroupLabel asChild>
          <CollapsibleTrigger>
            Help
            <ChevronDown className="ml-auto transition-transform group-data-[state=open]/collapsible:rotate-180" />
          </CollapsibleTrigger>
        </SidebarGroupLabel>
        <CollapsibleContent>
          <SidebarGroupContent />
        </CollapsibleContent>
      </SidebarGroup>
    </Collapsible>
  )
}

Note: We wrap the CollapsibleTrigger in a SidebarGroupLabel to render a button.

SidebarGroupAction

Use the SidebarGroupAction component to add an action button to the SidebarGroup.

export function AppSidebar() {
  return (
    <SidebarGroup>
      <SidebarGroupLabel asChild>Projects</SidebarGroupLabel>
      <SidebarGroupAction title="Add Project">
        <Plus /> <span className="sr-only">Add Project</span>
      </SidebarGroupAction>
      <SidebarGroupContent />
    </SidebarGroup>
  )
}

demo-sidebar-group-action — A sidebar group with an action button.

SidebarMenu

The SidebarMenu component is used for building a menu within a SidebarGroup.

A SidebarMenu component is composed of SidebarMenuItem, SidebarMenuButton, <SidebarMenuAction /> and <SidebarMenuSub /> components.

Here's an example of a SidebarMenu component rendering a list of projects.

demo-sidebar-menu — A sidebar menu with a list of projects.

<Sidebar>
  <SidebarContent>
    <SidebarGroup>
      <SidebarGroupLabel>Projects</SidebarGroupLabel>
      <SidebarGroupContent>

          {projects.map((project) => (
            <SidebarMenuItem key={project.name}>
              <SidebarMenuButton asChild>
                <a href={project.url}>
                  <project.icon />
                  <span>{project.name}</span>
                </a>
              </SidebarMenuButton>
            </SidebarMenuItem>
          ))}
        </SidebarMenu>
      </SidebarGroupContent>
    </SidebarGroup>
  </SidebarContent>
</Sidebar>

SidebarMenuButton

The SidebarMenuButton component is used to render a menu button within a SidebarMenuItem.

Link or Anchor

By default, the SidebarMenuButton renders a button but you can use the asChild prop to render a different component such as a Link or an a tag.

<SidebarMenuButton asChild>
  <a href="#">Home</a>
</SidebarMenuButton>

Icon and Label

You can render an icon and a truncated label inside the button. Remember to wrap the label in a <span>.

<SidebarMenuButton asChild>
  <a href="#">
    <Home />
    <span>Home</span>
  </a>
</SidebarMenuButton>

isActive

Use the isActive prop to mark a menu item as active.

<SidebarMenuButton asChild isActive>
  <a href="#">Home</a>
</SidebarMenuButton>

SidebarMenuAction

The SidebarMenuAction component is used to render a menu action within a SidebarMenuItem.

This button works independently of the SidebarMenuButton i.e you can have the <SidebarMenuButton /> as a clickable link and the <SidebarMenuAction /> as a button.

<SidebarMenuItem>
  <SidebarMenuButton asChild>
    <a href="#">
      <Home />
      <span>Home</span>
    </a>
  </SidebarMenuButton>
  <SidebarMenuAction>
    <Plus /> <span className="sr-only">Add Project</span>
  </SidebarMenuAction>
</SidebarMenuItem>

DropdownMenu

Here's an example of a SidebarMenuAction component rendering a DropdownMenu.

demo-sidebar-menu-action — A sidebar menu action with a dropdown menu.

<SidebarMenuItem>
  <SidebarMenuButton asChild>
    <a href="#">
      <Home />
      <span>Home</span>
    </a>
  </SidebarMenuButton>
  <DropdownMenu>
    <DropdownMenuTrigger asChild>
      <SidebarMenuAction>
        <MoreHorizontal />
      </SidebarMenuAction>
    </DropdownMenuTrigger>
    <DropdownMenuContent side="right" align="start">
      <DropdownMenuItem>
        <span>Edit Project</span>
      </DropdownMenuItem>
      <DropdownMenuItem>
        <span>Delete Project</span>
      </DropdownMenuItem>
    </DropdownMenuContent>
  </DropdownMenu>
</SidebarMenuItem>

SidebarMenuSub

The SidebarMenuSub component is used to render a submenu within a SidebarMenu.

Use <SidebarMenuSubItem /> and <SidebarMenuSubButton /> to render a submenu item.

demo-sidebar-menu-sub — A sidebar menu with a submenu.

<SidebarMenuItem>
  <SidebarMenuButton />
  <SidebarMenuSub>
    <SidebarMenuSubItem>
      <SidebarMenuSubButton />
    </SidebarMenuSubItem>
    <SidebarMenuSubItem>
      <SidebarMenuSubButton />
    </SidebarMenuSubItem>
  </SidebarMenuSub>
</SidebarMenuItem>

Collapsible SidebarMenu

To make a SidebarMenu component collapsible, wrap it and the SidebarMenuSub components in a Collapsible.

demo-sidebar-menu-collapsible — A collapsible sidebar menu.

<SidebarMenu>
  <Collapsible defaultOpen className="group/collapsible">
    <SidebarMenuItem>
      <CollapsibleTrigger asChild>
        <SidebarMenuButton />
      </CollapsibleTrigger>
      <CollapsibleContent>
        <SidebarMenuSub>
          <SidebarMenuSubItem />
        </SidebarMenuSub>
      </CollapsibleContent>
    </SidebarMenuItem>
  </Collapsible>
</SidebarMenu>

SidebarMenuBadge

The SidebarMenuBadge component is used to render a badge within a SidebarMenuItem.

<SidebarMenuItem>
  <SidebarMenuButton />
  <SidebarMenuBadge>24</SidebarMenuBadge>
</SidebarMenuItem>

SidebarMenuSkeleton

The SidebarMenuSkeleton component is used to render a skeleton for a SidebarMenu. You can use this to show a loading state when using React Server Components, SWR or react-query.

function NavProjectsSkeleton() {
  return (
    <SidebarMenu>
      {Array.from({ length: 5 }).map((_, index) => (
        <SidebarMenuItem key={index}>
          <SidebarMenuSkeleton />
        </SidebarMenuItem>
      ))}
    </SidebarMenu>
  )
}

SidebarSeparator

The SidebarSeparator component is used to render a separator within a Sidebar.

<Sidebar>
  <SidebarHeader />
  <SidebarSeparator />
  <SidebarContent>
    <SidebarGroup />
    <SidebarSeparator />
    <SidebarGroup />
  </SidebarContent>
</Sidebar>

SidebarTrigger

Use the SidebarTrigger component to render a button that toggles the sidebar.

The SidebarTrigger component must be used within a SidebarProvider.

<SidebarProvider>
  <Sidebar />
  <main>
    <SidebarTrigger />
  </main>
</SidebarProvider>

Custom Trigger

To create a custom trigger, you can use the useSidebar hook.

import { useSidebar } from "@/components/ui/sidebar"
 
export function CustomTrigger() {
  const { toggleSidebar } = useSidebar()
 
  return <button onClick={toggleSidebar}>Toggle Sidebar</button>
}

SidebarRail

The SidebarRail component is used to render a rail within a Sidebar. This rail can be used to toggle the sidebar.

<Sidebar>
  <SidebarHeader />
  <SidebarContent>
    <SidebarGroup />
  </SidebarContent>
  <SidebarFooter />
  <SidebarRail />
</Sidebar>

Data Fetching

React Server Components

Here's an example of a SidebarMenu component rendering a list of projects using React Server Components.

demo-sidebar-rsc — A sidebar menu using React Server Components.

Skeleton to show loading state.

function NavProjectsSkeleton() {
  return (
    <SidebarMenu>
      {Array.from({ length: 5 }).map((_, index) => (
        <SidebarMenuItem key={index}>
          <SidebarMenuSkeleton showIcon />
        </SidebarMenuItem>
      ))}
    </SidebarMenu>
  )
}

Server component fetching data.

async function NavProjects() {
  const projects = await fetchProjects()
 
  return (
    <SidebarMenu>
      {projects.map((project) => (
        <SidebarMenuItem key={project.name}>
          <SidebarMenuButton asChild>
            <a href={project.url}>
              <project.icon />
              <span>{project.name}</span>
            </a>
          </SidebarMenuButton>
        </SidebarMenuItem>
      ))}
    </SidebarMenu>
  )
}

Usage with React Suspense.

function AppSidebar() {
  return (
    <Sidebar>
      <SidebarContent>
        <SidebarGroup>
          <SidebarGroupLabel>Projects</SidebarGroupLabel>
          <SidebarGroupContent>
            <React.Suspense fallback={<NavProjectsSkeleton />}>
              <NavProjects />
            </React.Suspense>
          </SidebarGroupContent>
        </SidebarGroup>
      </SidebarContent>
    </Sidebar>
  )
}

SWR and React Query

You can use the same approach with SWR or react-query.

SWR

function NavProjects() {
  const { data, isLoading } = useSWR("/api/projects", fetcher)
 
  if (isLoading) {
    return (
      <SidebarMenu>
        {Array.from({ length: 5 }).map((_, index) => (
          <SidebarMenuItem key={index}>
            <SidebarMenuSkeleton showIcon />
          </SidebarMenuItem>
        ))}
      </SidebarMenu>
    )
  }
 
  if (!data) {
    return ...
  }
 
  return (
    <SidebarMenu>
      {data.map((project) => (
        <SidebarMenuItem key={project.name}>
          <SidebarMenuButton asChild>
            <a href={project.url}>
              <project.icon />
              <span>{project.name}</span>
            </a>
          </SidebarMenuButton>
        </SidebarMenuItem>
      ))}
    </SidebarMenu>
  )
}

React Query

function NavProjects() {
  const { data, isLoading } = useQuery()
 
  if (isLoading) {
    return (
      <SidebarMenu>
        {Array.from({ length: 5 }).map((_, index) => (
          <SidebarMenuItem key={index}>
            <SidebarMenuSkeleton showIcon />
          </SidebarMenuItem>
        ))}
      </SidebarMenu>
    )
  }
 
  if (!data) {
    return ...
  }
 
  return (
    <SidebarMenu>
      {data.map((project) => (
        <SidebarMenuItem key={project.name}>
          <SidebarMenuButton asChild>
            <a href={project.url}>
              <project.icon />
              <span>{project.name}</span>
            </a>
          </SidebarMenuButton>
        </SidebarMenuItem>
      ))}
    </SidebarMenu>
  )
}

Controlled Sidebar

Use the open and onOpenChange props to control the sidebar.

demo-sidebar-controlled — A controlled sidebar.

export function AppSidebar() {
  const [open, setOpen] = React.useState(false)
 
  return (
    <SidebarProvider open={open} onOpenChange={setOpen}>
      <Sidebar />
    </SidebarProvider>
  )
}

Theming

We use the following CSS variables to theme the sidebar.

@layer base {
  :root {
    --sidebar-background: 0 0% 98%;
    --sidebar-foreground: 240 5.3% 26.1%;
    --sidebar-primary: 240 5.9% 10%;
    --sidebar-primary-foreground: 0 0% 98%;
    --sidebar-accent: 240 4.8% 95.9%;
    --sidebar-accent-foreground: 240 5.9% 10%;
    --sidebar-border: 220 13% 91%;
    --sidebar-ring: 217.2 91.2% 59.8%;
  }
 
  .dark {
    --sidebar-background: 240 5.9% 10%;
    --sidebar-foreground: 240 4.8% 95.9%;
    --sidebar-primary: 0 0% 98%;
    --sidebar-primary-foreground: 240 5.9% 10%;
    --sidebar-accent: 240 3.7% 15.9%;
    --sidebar-accent-foreground: 240 4.8% 95.9%;
    --sidebar-border: 240 3.7% 15.9%;
    --sidebar-ring: 217.2 91.2% 59.8%;
  }
}

We intentionally use different variables for the sidebar and the rest of the application to make it easy to have a sidebar that is styled differently from the rest of the application. Think a sidebar with a darker shade from the main application.

Styling

Here are some tips for styling the sidebar based on different states.

Styling an element based on the sidebar collapsible state. The following will hide the SidebarGroup when the sidebar is in icon mode.

<Sidebar collapsible="icon">
  <SidebarContent>
    <SidebarGroup className="group-data-[collapsible=icon]:hidden" />
  </SidebarContent>
</Sidebar>

Styling a menu action based on the menu button active state. The following will force the menu action to be visible when the menu button is active.

<SidebarMenuItem>
  <SidebarMenuButton />
  <SidebarMenuAction className="peer-data-[active=true]/menu-button:opacity-100" />
</SidebarMenuItem>

You can find more tips on using states for styling in this Twitter thread.

#5593 - Improved setOpen callback logic in <SidebarProvider>.

Update the setOpen callback in <SidebarProvider> as follows:

const setOpen = React.useCallback(
  (value: boolean | ((value: boolean) => boolean)) => {
    const openState = typeof value === "function" ? value(open) : value
    if (setOpenProp) {
      setOpenProp(openState)
    } else {
      _setOpen(openState)
    }
 
    // This sets the cookie to keep the sidebar state.
    document.cookie = `${SIDEBAR_COOKIE_NAME}=${openState}; path=/; max-age=${SIDEBAR_COOKIE_MAX_AGE}`
  },
  [setOpenProp, open]
)
