Usage
Example with defaultSize
<Resizable
defaultSize={{
width:320,
height:200,
}}
>
Sample with default size
</Resizable>
Example with size
If you use size
props, please manage state by yourself.
<Resizable
size={{ width: this.state.width, height: this.state.height }}
onResizeStop={(e, direction, ref, d) => {
this.setState({
width: this.state.width + d.width,
height: this.state.height + d.height,
});
}}
>
Sample with size
</Resizable>
Props
defaultSize?: { width: (number | string), height: (number | string) };
Specifies the width
and height
that the dragged item should start at.
For example, you can set 300
, '300px'
, 50%
.
If both defaultSize
and size
omitted, set 'auto'
.
defaultSize
will be ignored when size
set.
size?: { width: (number | string), height: (number | string) };
The size
property is used to set the size of the component.
For example, you can set 300
, '300px'
, 50%
.
Use size
if you need to control size state by yourself.
className?: string;
The className
property is used to set the custom className
of a resizable component.
style?: { [key: string]: string };
The style
property is used to set the custom style
of a resizable component.
minWidth?: number | string;
The minWidth
property is used to set the minimum width of a resizable component. Defaults to 10px.
It accepts viewport as well as parent relative units. For example, you can set 300
, 50%
, 50vw
or 50vh
.
Same type of values can be applied to minHeight
, maxWidth
and maxHeight
.
minHeight?: number | string;
The minHeight
property is used to set the minimum height of a resizable component. Defaults to 10px.
maxWidth?: number | string;
The maxWidth
property is used to set the maximum width of a resizable component.
maxHeight?: number | string
;
The maxHeight
property is used to set the maximum height of a resizable component.
grid?: [number, number];
The grid
property is used to specify the increments that resizing should snap to. Defaults to [1, 1]
.
snap?: { x?: Array<number>, y?: Array<number> };
The snap
property is used to specify absolute pixel values that resizing should snap to. x
and y
are both optional, allowing you to only include the axis you want to define. Defaults to null
.
snapGap?: number
The snapGap
property is used to specify the minimum gap required in order to move to the next snapping target. Defaults to 0
which means that snap targets are always used.
resizeRatio?: number | string;
The resizeRatio
property is used to set the number of pixels the resizable component scales by compared to the number of pixels the mouse/touch moves. Defaults to 1
(for a 1:1 ratio). The number set is the left side of the ratio, 2
will give a 2:1 ratio.
lockAspectRatio?: boolean | number;
The lockAspectRatio
property is used to lock aspect ratio.
Set to true
to lock the aspect ratio based on the initial size.
Set to a numeric value to lock a specific aspect ratio (such as 16/9
).
If set to numeric, make sure to set initial height/width to values with correct aspect ratio.
If omitted, set false
.
lockAspectRatioExtraWidth?: number;
The lockAspectRatioExtraWidth
property enables a resizable component to maintain an aspect ratio plus extra width.
For instance, a video could be displayed 16:9 with a 50px side bar.
If omitted, set 0
.
lockAspectRatioExtraHeight?: number;
The lockAspectRatioExtraHeight
property enables a resizable component to maintain an aspect ratio plus extra height.
For instance, a video could be displayed 16:9 with a 50px header bar.
If omitted, set 0
.
bounds?: ('window' | 'parent' | HTMLElement);
Specifies resize boundaries.
handleStyles?: HandleStyles;
The handleStyles
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.
handleClasses?: HandleClassName;
The handleClasses
property is used to set the className of one or more resize handles.
handleComponent?: HandleComponent;
The handleComponent
property is used to pass a React Component to be rendered as one or more resize handle. For example, this could be used to use an arrow icon as a handle..
handleWrapperStyle?: { [key: string]: string };
The handleWrapperStyle
property is used to override the style of resize handles wrapper.
handleWrapperClass?: string;
The handleWrapperClass
property is used to override the className of resize handles wrapper.
enable?: ?Enable;
The enable
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 }
.
onResizeStart?: ResizeStartCallBack;
ResizeStartCallBack
type is below.
type ResizeStartCallback = (
e: SyntheticMouseEvent<HTMLDivElement> | SyntheticTouchEvent<HTMLDivElement>,
dir: ResizableDirection,
refToElement: HTMLDivElement,
) => void;
Calls when resizable component resize start.
onResize?: ResizeCallback;
scale?: number
;
The scale
property is used in the scenario where the resizable element is a descendent of an element using css scaling (e.g. - transform: scale(0.5)
).
as?: string | React.ComponentType

direction: ResizableDirection,
refToElement: HTMLDivElement,
delta: NumberSize,
) => void;
Calls when resizable component resizing.
onResizeStop?: ResizeCallback;
ResizeCallback
type is below.
type ResizeCallback = (
event: MouseEvent | TouchEvent,
direction: ResizableDirection,
