Add Resizable

Base UI / canonicalnpx shadcn@latest add https://gummyui.dev/r/gummy-resizable.json

No package dependency beyond React. Shared Gummy material is resolved automatically.

Behavior contract

Semantics before surface

Semantics

A focusable separator exposes orientation and current/min/max values.

Keyboard

Arrows resize; Shift accelerates; Home/End use the bounds.

System support

Light and dark themes, logical RTL layout, reduced motion, responsive content, and forwarded public refs.

Source-derived reference

Anatomy and public API

Exported anatomy

These public React parts are read directly from the canonical source during the documentation build.

Prop contracts

`GummyResizableHandleProps`

Composes React.HTMLAttributes<HTMLDivElement> & { label?: string; step?: number; }

`GummyResizablePanelGroupProps`

Composes Omit< React.HTMLAttributes<HTMLDivElement>, "onChange" | "dir" > & { orientation?: "horizontal" | "vertical"; direction?: "ltr" | "rtl"; size?: number; defaultSize?: number; minSize?: number; maxSize?: number; onSizeChange?: (size: number) => void; }

`GummyResizablePanelProps`

Composes React.HTMLAttributes<HTMLDivElement> & { order: "first" | "second"; }

Troubleshooting

Check behavior before surface.

If the material is missing, confirm the registry-installed shared and component CSS files are imported once.
If interaction differs, preserve this contract: Arrows resize; Shift accelerates; Home/End use the bounds.
If assistive output differs, preserve this semantic foundation: A focusable separator exposes orientation and current/min/max values.
If dark, RTL, or reduced-motion behavior is missing, verify the nearest theme, direction, and media-query boundaries rather than adding page-local overrides.

The Component Lab exercises real source across default, focus, disabled, responsive, dark, reduced-motion, and RTL contexts.

Try Resizable in context

Resize the canvas, switch its theme, or reverse its reading direction without changing the rest of the page.
