import {
  ResizableHandle,
  ResizablePanel,
  ResizablePanelGroup,
} from "@/components/ui/resizable"

## Examples

### Vertical

通过 `direction` 属性控制面板的伸缩方向。

```tsx
import {
  ResizableHandle,
  ResizablePanel,
  ResizablePanelGroup,
} from "@/components/ui/resizable"

export function ResizableDemo() {
  return (
    <ResizablePanelGroup
      direction="vertical"
      className="min-h-[200px] max-w-md rounded-lg border md:min-w-[450px]"
    >
      <ResizablePanel defaultSize={25}>
        <div className="flex h-full items-center justify-center p-6">
          <span className="font-semibold">Header</span>
        </div>
      </ResizablePanel>
      <ResizableHandle />
      <ResizablePanel defaultSize={75}>
        <div className="flex h-full items-center justify-center p-6">
          <span className="font-semibold">Content</span>
        </div>
      </ResizablePanel>
    </ResizablePanelGroup>
  )
}

```

```tsx showLineNumbers {9}
import {
  ResizableHandle,
  ResizablePanel,
  ResizablePanelGroup,
} from "@/components/ui/resizable"

export default function Example() {
  return (
    <ResizablePanelGroup direction="vertical">
      <ResizablePanel>面板一</ResizablePanel>
      <ResizableHandle />
      <ResizablePanel>面板二</ResizablePanel>
    </ResizablePanelGroup>
  )
}
```

### Handle

可通过 `ResizableHandle` 的 `withHandle` 属性设置或隐藏拖拽手柄。

```tsx
import {
  ResizableHandle,
  ResizablePanel,
  ResizablePanelGroup,
} from "@/components/ui/resizable"

export function ResizableHandleDemo() {
  return (
    <ResizablePanelGroup
      direction="horizontal"
      className="min-h-[200px] max-w-md rounded-lg border md:min-w-[450px]"
    >
      <ResizablePanel defaultSize={25}>
        <div className="flex h-full items-center justify-center p-6">
          <span className="font-semibold">Sidebar</span>
        </div>
      </ResizablePanel>
      <ResizableHandle withHandle />
      <ResizablePanel defaultSize={75}>
        <div className="flex h-full items-center justify-center p-6">
          <span className="font-semibold">Content</span>
        </div>
      </ResizablePanel>
    </ResizablePanelGroup>
  )
}

```

```tsx showLineNumbers {11}
import {
  ResizableHandle,
  ResizablePanel,
  ResizablePanelGroup,
} from "@/components/ui/resizable"

export default function Example() {
  return (
    <ResizablePanelGroup direction="horizontal">
      <ResizablePanel>面板一</ResizablePanel>
      <ResizableHandle withHandle />
      <ResizablePanel>面板二</ResizablePanel>
