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*.vue
.
We now have a solid foundation to build on top of. Composable. Themeable. Customizable.
Installation
Run the following command to install sidebar
npx shadcn-vue@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.
@layer base {
:root {
--sidebar-background: 0 0% 98%;
--sidebar-foreground: 240 5.3% 26.1%;

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.
<script setup lang="ts">
import { AppSidebar } from '@/components/app-sidebar'
import { SidebarProvider, SidebarTrigger } from '@/components/ui/sidebar'
</script>
<template>
<SidebarProvider>
<AppSidebar />
<main>
<SidebarTrigger />
<slot />
</main>
</SidebarProvider>
</template>
Create a new sidebar component at components/AppSidebar.vue
.
<script setup lang="ts">
import { Sidebar, SidebarContent } from '@/components/ui/sidebar'
</script>
<template>
<Sidebar>
<SidebarContent />
</Sidebar>
</template>
Now, let's add a SidebarMenu
to the sidebar.
We'll use the SidebarMenu
component in a SidebarGroup
.
<script setup lang="ts">
import {
Sidebar,
SidebarContent,
SidebarGroup,
SidebarGroupContent,
SidebarGroupLabel,
SidebarMenu,
SidebarMenuButton,
SidebarMenuItem,
} from '@/components/ui/sidebar'
import { Calendar, Home, Inbox, Search, Settings } from 'lucide-vue-next'
// 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 },
]
</script>
<template>
<Sidebar>
<SidebarContent>
<SidebarGroup>
<SidebarGroupLabel>Application</SidebarGroupLabel>
<SidebarGroupContent>
<SidebarMenu>
<SidebarMenuItem v-for="item in items" :key="item.title">
<SidebarMenuButton asChild>
<a :href="item.url">
<component :is="item.icon" />
<span>{{item.title}}</span>
</a>
</SidebarMenuButton>
</SidebarMenuItem>
</SidebarMenu>
</SidebarGroupContent>
</SidebarGroup>
</SidebarContent>
</Sidebar>
</template>
You've created your first sidebar.
Components
The components in Sidebar*
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*.vue
, you are encouraged to do so. The code is yours. Use Sidebar.vue
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/utils
to set the width of the sidebar.
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.
<template>
<SidebarProvider
:style="{
'--sidebar-width': '20rem',
'--sidebar-width-mobile': '20rem',
}"
>
<Sidebar />
</SidebarProvider>
</template>
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.
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 Nuxt, set up your SidebarProvider
in app/layout.tsx
like this:
<script setup lang="ts">
import AppSidebar from '@/components/AppSidebar.vue'
import { SidebarProvider, SidebarTrigger } from '@/components/ui/sidebar'
const sidebarState = useCookie('sidebar:state')
const defaultOpen = computed(() => sidebarState.value === 'true')
</script>
<template>
<SidebarProvider :defaultOpen="defaultOpen">
<AppSidebar />
<main>
<SidebarTrigger />
<slot />
</main>
</SidebarProvider>
</template>
You can change the name of the cookie by updating the SIDEBAR_COOKIE_NAME
variable in sidebar/utils
.
const SIDEBAR_COOKIE_NAME = 'sidebar:state'

.
<template>
<SidebarProvider>
<Sidebar />
<main>
<SidebarTrigger />
</main>
</SidebarProvider>
</template>
Custom Trigger
To create a custom trigger, you can use the useSidebar
hook.
<script setup lang="ts">
import { useSidebar } from '@/components/ui/sidebar'
const { toggleSidebar } = useSidebar()
</script>
<template>
<button @click="toggleSidebar">Toggle Sidebar</button>
</template>
SidebarRail

<template>
<Sidebar>
<SidebarHeader />
<SidebarContent>
<SidebarGroup />

</Sidebar>
</template>
Controlled Sidebar
Use the open
and onOpenChange
props to control the sidebar.
<script setup lang="ts">
const open = ref(false)
</script>
<template>
<SidebarProvider v-model:open="open">
<Sidebar />
</SidebarProvider>
</template>
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 inicon
mode.
<template>
<Sidebar collapsible="icon">
<SidebarContent>
<SidebarGroup class="group-data-[collapsible=icon]:hidden" />
</SidebarContent>
</Sidebar>
</template>
- 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.
<template>
<SidebarMenuItem>
<SidebarMenuButton />
<SidebarMenuAction class="peer-data-[active=true]/menu-button:opacity-100" />
</SidebarMenuItem>
</template>
You can find more tips on using states for styling in this Twitter thread.
