8-bit Resizable Panel

An 8-bit-styled wrapper around `react-resizable-panels` for building accessible, resizable panel groups. It exports a panel group, panel, and separator handle, with an optional visual grip on the handle.

Installation

pnpm dlx shadcn@latest add @8bitcn/resizable

Requires @8bitcn in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import { ResizableHandle, ResizablePanel, ResizablePanelGroup } from "@/components/ui/8bit/resizable";<ResizablePanelGroup direction="horizontal">  <ResizablePanel>Navigation</ResizablePanel>  <ResizableHandle withHandle />  <ResizablePanel>Workspace</ResizablePanel></ResizablePanelGroup>
  • When users need to adjust the relative space given to adjacent content areas.
  • For split-pane interfaces such as an editor beside a preview, or a sidebar beside a workspace.
  • When a resizable layout should have a retro, pixel-inspired visual treatment.

API reference

PropTypeDefaultDescription
ResizablePanelGroup: primitive propsReact.ComponentProps<typeof ResizablePrimitive.Group>—Accepts and forwards the group primitive's props. `className` is applied to the outer wrapper; the primitive receives its own fixed layout classes. `children` are rendered inside the primitive group.
ResizablePanel: primitive propsReact.ComponentProps<typeof ResizablePrimitive.Panel>—Accepts and forwards the panel primitive's props. `className` is applied to the panel and `children` are rendered inside it.
ResizableHandle: primitive propsReact.ComponentProps<typeof ResizablePrimitive.Separator>—Accepts and forwards the separator primitive's props. `className` is merged with the handle's default styling.
ResizableHandle: withHandleboolean—Optional wrapper prop. When true, renders an additional small rectangular visual grip inside the separator.

Accessibility

  • The group, panels, and separator are based on `react-resizable-panels` primitives, whose props and interaction behavior are forwarded by the wrappers.
  • The separator includes visible focus styling using `focus-visible` ring classes.
  • The optional grip is an added visual element; it does not replace the separator's primitive interaction or accessibility behavior.
