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>
  );
}

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 a 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.

className?: string;

The className property is used to set the custom className of the component.

style?: { [key: string]: string };

The style property is used to set the custom style of the component.

minWidth?: number | string;

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

minHeight?: number | string;

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

maxWidth?: number | string;

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

maxHeight?: number | string;

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

z?: number;

The z property is used to set the zIndex of a component.

resizeGrid?: [number, number];

The resizeGrid property is used to specify the increments that resizing should snap to. Defaults to [1, 1].

dragGrid?: [number, number];

The dragGrid property is used to specify the increments that moving should snap to. Defaults to [1, 1].

lockAspectRatio?: boolean;

The lockAspectRatio property is used to lock aspect ratio. If omitted, set false.

dragHandleClassName?: string;

Specifies a selector to be used as the handle that initiates drag. Example: '.handle'.

resizeHandleStyles?: HandleStyles;

The resizeHandleStyles property is used to override the style of one or more resize handles. Only the axis you specify will have its handle style replaced. If you specify a value for right it will completely replace the styles for the right resize handle, but other handle will still use the default styles.

type Style = { [key: string]: string };

export type HandleStyles = {
  bottom?: Style,
  bottomLeft?: Style,
  bottomRight?: Style,
  left?: Style,
  right?: Style,
  top?: Style,
  topLeft?: Style,
  topRight?: Style
}

resizeHandleClasses?: HandleClasses;

The resizeHandleClasses property is used to set the className of one or more resize handles.

type HandleClasses = {
  bottom?: string;
  bottomLeft?: string;
  bottomRight?: string;
  left?: string;
  right?: string;
  top?: string;
  topLeft?: string;
  topRight?: string;
}

enableResizing?: ?Enable;

The enableResizing property is used to set the resizable permission of the component.

The permission of top, right, bottom, left, topRight, bottomRight, bottomLeft, topLeft direction resizing. If omitted, all resizer are enabled. If you want to permit only right direction resizing, set { top:false, right:true, bottom:false, left:false, topRight:false, bottomRight:false, bottomLeft:false, topLeft:false }.

export type Enable = {
  bottom?: boolean;
  bottomLeft?: boolean;
  bottomRight?: boolean;
  left?: boolean;
  right?: boolean;
  top?: boolean;
  topLeft?: boolean;
  topRight?: boolean;
}

disableDragging?: boolean;

The disableDragging property disables dragging completely.

extendsProps?: { [key: string]: any };

This property is used to pass the other props to the component.

e.g.

const extendsProps = {
  data-foo: 'foo',
  onMouseOver: () => {},
};

<Rnd extendsProps={extendsProps} />

dragAxis?: 'x' | 'y' | 'both' | 'none'

The direction of allowed movement (dragging) allowed ('x','y','both','none').

bounds?: string;

Specifies movement boundaries. Accepted values:

• parent restricts movement within the node's offsetParent (nearest node with position relative or absolute), or
• Selector, like .fooClassName.
