react-rnd

What is react-rnd?

The react-rnd package is a React component that allows you to create resizable and draggable elements. It is highly customizable and can be used to build complex user interfaces with ease.

What are react-rnd's main functionalities?

Draggable

This feature allows you to make any element draggable. The code sample demonstrates how to create a draggable component with default position and size.

import Rnd from 'react-rnd';

function DraggableComponent() {
  return (
    <Rnd
      default={{ x: 0, y: 0, width: 320, height: 200 }}
    >
      <div style={{ border: '1px solid black', padding: '10px' }}>
        Draggable Content
      </div>
    </Rnd>
  );
}

Resizable

This feature allows you to make any element resizable. The code sample demonstrates how to create a resizable component with resizing enabled on all sides and corners.

import Rnd from 'react-rnd';

function ResizableComponent() {
  return (
    <Rnd
      default={{ x: 0, y: 0, width: 320, height: 200 }}
      enableResizing={{ top: true, right: true, bottom: true, left: true, topRight: true, bottomRight: true, bottomLeft: true, topLeft: true }}
    >
      <div style={{ border: '1px solid black', padding: '10px' }}>
        Resizable Content
      </div>
    </Rnd>
  );
}

Draggable and Resizable

This feature allows you to make any element both draggable and resizable. The code sample demonstrates how to create a component that can be dragged and resized.

import Rnd from 'react-rnd';

function DraggableResizableComponent() {
  return (
    <Rnd
      default={{ x: 0, y: 0, width: 320, height: 200 }}
      enableResizing={{ top: true, right: true, bottom: true, left: true, topRight: true, bottomRight: true, bottomLeft: true, topLeft: true }}
    >
      <div style={{ border: '1px solid black', padding: '10px' }}>
        Draggable and Resizable Content
      </div>
    </Rnd>
  );
}

Usage

Example with default

<Rnd
  default={{
    x: 0,
    y: 0,
    width: 320,
    height: 200,
  }}
>
  Rnd
</Rnd>

Example with position and size

<Rnd
  size={{ width: this.state.width,  height: this.state.height }}
  position={{ x: this.state.x, y: this.state.y }}
  onDragStop={(e, d) => { this.setState({ x: d.x, y: d.y }) }}
  onResize={(e, direction, ref, delta, position) => {
    this.setState({
      width: ref.offsetWidth,
      height: ref.offsetHeight,
      ...position,
    });
  }}
>
  001
</Rnd>

Example

You can try it on WebpackBin too.

Props

default: { x: number; y: number; width?: number | string; height?: number | string; };

The width and height property is used to set the default size of the component. For example, you can set 300, '300px', 50%.
If omitted, set 'auto'.

The x and y property is used to set the default position of the component.

size?: { width: (number | string), height: (number | string) };

The size property is used to set size of the component. For example, you can set 300, '300px', 50%.

Use size if you need to control size state by yourself.

position?: { x: number, y: number };

The position property is used to set position of the component. Use position if you need to control size state by yourself.

see, following example.

<Rnd
  size={{ width: this.state.width,  height: this.state.height }}
  position={{ x: this.state.x, y: this.state.y }}
  onDragStop={(e, d) => { this.setState({ x: d.x, y: d.y }) }}
  onResize={(e, direction, ref, delta, position) => {
    this.setState({
      width: ref.offsetWidth,
      height: ref.offsetHeight,
      ...position,
    });
  }}
>
  001
</Rnd>
