侧边栏
可组合、可主题化和可自定义的侧边栏组件。
侧边栏是最复杂的组件之一。它们是任何应用的核心,通常包含许多活动部件。
¥Sidebars are one of the most complex components to build. They are central to any application and often contain a lot of moving parts.
我不喜欢构建侧边栏。所以我构建了 30 多个。各种配置。然后我将核心组件提取到 sidebar.tsx
中。
¥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
.
我们现在有一个坚实的基础可以在此基础上构建。可组合。可主题化。可定制。
¥We now have a solid foundation to build on top of. Composable. Themeable. Customizable.

}
你的第一个侧边栏
¥Your First Sidebar
让我们从最基本的侧边栏开始。带有菜单的可折叠侧边栏。
¥Let's start with the most basic sidebar. A collapsible sidebar with a menu.
在应用的根目录下添加 SidebarProvider
和 SidebarTrigger
。
¥Add a SidebarProvider
and SidebarTrigger
at the root of your application.
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
.
import { Sidebar, SidebarContent } from "@/components/ui/sidebar"
export function AppSidebar() {
return (
<Sidebar>
<SidebarContent />
</Sidebar>
)
}
Now, let's add a SidebarMenu
to the sidebar.
我们将在 SidebarGroup
中使用 SidebarMenu
组件。
¥We'll use the SidebarMenu
component in a SidebarGroup
.
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.
组件
¥Components
sidebar.tsx
中的组件是可组合的,即你可以通过将提供的组件放在一起来构建侧边栏。它们还可以与其他 shadcn/ui 组件(如 DropdownMenu
、Collapsible
或 Dialog
等)很好地组合。
¥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.
如果你需要更改 sidebar.tsx
中的代码,我们鼓励你这样做。代码是你的。使用 sidebar.tsx
作为起点并构建你自己的。
¥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.
在接下来的部分中,我们将介绍每个组件及其使用方法。
¥In the next sections, we'll go over each component and how to use them.
SidebarProvider
SidebarProvider
组件用于为 Sidebar
组件提供侧边栏上下文。你应该始终将你的应用封装在 SidebarProvider
组件中。
¥The SidebarProvider
component is used to provide the sidebar context to the Sidebar
component. You should always wrap your application in a SidebarProvider
component.
属性
¥Props
名称 | 类型 | 描述 |
---|---|---|
defaultOpen | boolean | 侧边栏的默认打开状态。 |
open | boolean | 侧边栏的打开状态(受控)。 |
onOpenChange | (open: boolean) => void | 设置侧边栏的打开状态(受控)。 |
宽度
¥Width
如果你的应用中只有一个侧边栏,则可以使用 sidebar.tsx
中的 SIDEBAR_WIDTH
和 SIDEBAR_WIDTH_MOBILE
变量来设置侧边栏的宽度。
¥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.
const SIDEBAR_WIDTH = "16rem"
const SIDEBAR_WIDTH_MOBILE = "18rem"
对于应用中的多个侧边栏,你可以使用 style
prop 来设置侧边栏的宽度。
¥For multiple sidebars in your application, you can use the style
prop to set the width of the sidebar.
要设置侧边栏的宽度,你可以在 style
属性中使用 --sidebar-width
和 --sidebar-width-mobile
CSS 变量。
¥To set the width of the sidebar, you can use the --sidebar-width
and --sidebar-width-mobile
CSS variables in the style
prop.
<SidebarProvider
style={{
"--sidebar-width": "20rem",
"--sidebar-width-mobile": "20rem",
}}
>
<Sidebar />
</SidebarProvider>
这将处理侧边栏的宽度以及布局间距。
¥This will handle the width of the sidebar but also the layout spacing.
键盘快捷方式
¥Keyboard Shortcut
SIDEBAR_KEYBOARD_SHORTCUT
变量用于设置用于打开和关闭侧边栏的键盘快捷键。
¥The SIDEBAR_KEYBOARD_SHORTCUT
variable is used to set the keyboard shortcut used to open and close the sidebar.
要触发侧边栏,请在 Mac 上使用 cmd+b
键盘快捷键,在 Windows 上使用 ctrl+b
。
¥To trigger the sidebar, you use the cmd+b
keyboard shortcut on Mac and ctrl+b
on Windows.
你可以通过更新 SIDEBAR_KEYBOARD_SHORTCUT
变量来更改键盘快捷键。
¥You can change the keyboard shortcut by updating the SIDEBAR_KEYBOARD_SHORTCUT
variable.
const SIDEBAR_KEYBOARD_SHORTCUT = "b"
持久状态
¥Persisted State
SidebarProvider
支持在页面重新加载和服务器端渲染时保持侧边栏状态。它使用 cookie 来存储侧边栏的当前状态。当侧边栏状态发生变化时,将使用当前打开/关闭状态设置一个名为 sidebar:state
的默认 cookie。然后在后续页面加载时读取此 cookie 以恢复侧边栏状态。
¥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.
要在 Next.js 中保留侧边栏状态,请在 app/layout.tsx
中像这样设置你的 SidebarProvider
:
¥To persist sidebar state in Next.js, set up your SidebarProvider
in app/layout.tsx
like this:
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>
)
}
你可以通过更新 sidebar.tsx
中的 SIDEBAR_COOKIE_NAME
变量来更改 cookie 的名称。
¥You can change the name of the cookie by updating the SIDEBAR_COOKIE_NAME
variable in sidebar.tsx
.
const SIDEBAR_COOKIE_NAME = "sidebar:state"

受控侧边栏
¥Controlled Sidebar
使用 open
和 onOpenChange
属性来控制侧边栏。
¥Use the open
and onOpenChange
props to control the sidebar.
export function AppSidebar() {
const [open, setOpen] = React.useState(false)
return (
<SidebarProvider open={open} onOpenChange={setOpen}>
<Sidebar />
</SidebarProvider>
)
}
主题
¥Theming
我们使用以下 CSS 变量来设置侧边栏的主题。
¥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%;
}
}
我们有意为侧边栏和应用的其余部分使用不同的变量,以便轻松拥有与应用其余部分不同样式的侧边栏。想象一下主应用中带有深色阴影的侧边栏。
¥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.
样式
¥Styling
以下是根据不同状态设置侧边栏样式的一些技巧。
¥Here are some tips for styling the sidebar based on different states.
-
根据侧边栏可折叠状态设置元素样式。当侧边栏处于
icon
模式时,以下内容将隐藏SidebarGroup
。¥Styling an element based on the sidebar collapsible state. The following will hide the
SidebarGroup
when the sidebar is inicon
mode.
<Sidebar collapsible="icon">
<SidebarContent>
<SidebarGroup className="group-data-[collapsible=icon]:hidden" />
</SidebarContent>
</Sidebar>
-
根据菜单按钮活动状态设置菜单操作的样式。以下内容将强制菜单操作在菜单按钮处于活动状态时可见。
¥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>
