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.
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 a resizable component.

style?: any;

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

width?: (number | string);

The width property is used to set the initial width of a resizable component.
For example, you can set 300, '300px', 50%.
If omitted, set 'auto'.

height?: (number | string);

The height property is used to set the initial height of a resizable component.
For example, you can set 300, '300px', 50%.
If omitted, set 'auto'.

minWidth?: number;

The minWidth property is used to set the minimum width of a resizable component.

minHeight?: number;

The minHeight property is used to set the minimum height of a resizable component.

maxWidth?: number;

The maxWidth property is used to set the maximum width of a resizable component.

maxHeight?: number;

The maxHeight property is used to set the maximum height of a resizable component.

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.

dragHandlerClassName?: string;

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

resizeHandlerStyles?: HandlersStyles;

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

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

resizeHandlerClasses?: HandlersClassName;

The resizeHandlerClasses property is used to set the className of one or more resize handlers.

type HandlerClasses = {
  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 a resizable 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?: boolea;
  topRight?: boolean;
}

extendsProps?: 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.
