Resizable
A set of wrappers around `react-resizable-panels` for creating resizable panel groups, panels, and separators. The group adds layout styles, while the separator can optionally display a small visual grip.

Usage
usage.tsx
import { ResizableHandle, ResizablePanel, ResizablePanelGroup } from "@/components/ui/resizable"export function Example() { return ( <ResizablePanelGroup orientation="horizontal"> <ResizablePanel defaultSize={30}>Sidebar</ResizablePanel> <ResizableHandle withHandle /> <ResizablePanel>Main content</ResizablePanel> </ResizablePanelGroup> )}- Let users adjust the relative space taken by adjacent content areas.
- Build split views such as an editor beside a preview or a sidebar beside a main pane.
- Provide a vertical resizable division, such as stacked panels.
Examples
Sidebar and content
A horizontal split between navigation and the main view.
sidebar-and-content.tsx
import { ResizableHandle, ResizablePanel, ResizablePanelGroup } from "@/components/ui/resizable"export function SidebarSplit() { return ( <ResizablePanelGroup orientation="horizontal"> <ResizablePanel defaultSize={25}>Navigation</ResizablePanel> <ResizableHandle withHandle /> <ResizablePanel>Main content</ResizablePanel> </ResizablePanelGroup> )}Editor and preview
A horizontal split for editable source and its preview.
editor-and-preview.tsx
import { ResizableHandle, ResizablePanel, ResizablePanelGroup } from "@/components/ui/resizable"export function EditorPreview() { return ( <ResizablePanelGroup orientation="horizontal"> <ResizablePanel defaultSize={50}>Editor</ResizablePanel> <ResizableHandle /> <ResizablePanel>Preview</ResizablePanel> </ResizablePanelGroup> )}Stacked panes
A vertical split between a workspace and a lower output area.
stacked-panes.tsx
import { ResizableHandle, ResizablePanel, ResizablePanelGroup } from "@/components/ui/resizable"export function StackedPanes() { return ( <ResizablePanelGroup orientation="vertical"> <ResizablePanel defaultSize={70}>Workspace</ResizablePanel> <ResizableHandle withHandle /> <ResizablePanel>Output</ResizablePanel> </ResizablePanelGroup> )}API reference
PropTypeDefaultDescription
ResizablePanelGroupResizablePrimitive.GroupProps—Accepts and forwards the `react-resizable-panels` Group props. `className` is combined with the wrapper's layout classes.
ResizablePanelResizablePrimitive.PanelProps—Accepts and forwards the `react-resizable-panels` Panel props.
ResizableHandleResizablePrimitive.SeparatorProps & { withHandle?: boolean }—Accepts and forwards the `react-resizable-panels` Separator props. `className` is combined with the wrapper's separator styles. `withHandle` optionally renders a small visual grip.
Accessibility
- The separator is rendered by the resizable-panels primitive; retain it as the interactive divider rather than treating the optional grip as the control.
- The separator styles include a visible focus outline for keyboard focus.
- The group and separator primitives provide orientation semantics used by the wrapper's orientation-dependent layout and styles.
