React-Grid-Layout is a grid layout system much like Packery or Gridster, for React.
Unlike those systems, it is responsive and supports breakpoints. Breakpoint layouts can be provided by the user or autogenerated.
RGL is React-only and does not require jQuery.

Install the React-Grid-Layout package using npm:
npm install react-grid-layoutInclude the following stylesheets in your application:
/node_modules/react-grid-layout/css/styles.css
/node_modules/react-resizable/css/styles.css
Use ReactGridLayout like any other component. The following example below will produce a grid with three items where:
- users will not be able to drag or resize item
a - item
bwill be restricted to a minimum width of 2 grid blocks and a maximum width of 4 grid blocks - users will be able to freely drag and resize item
c
import GridLayout from "react-grid-layout";
class MyFirstGrid extends React.Component {
render() {
// layout is an array of objects, see the demo for more complete usage
const layout = [
{ i: "a", x: 0, y: 0, w: 1, h: 2, static: true },
{ i: "b", x: 1, y: 0, w: 3, h: 2, minW: 2, maxW: 4 },
{ i: "c", x: 4, y: 0, w: 1, h: 2 }
];
return (
<GridLayout
className="layout"
layout={layout}
cols={12}
rowHeight={30}
width={1200}
>
<div key="a">a</div>
<div key="b">b</div>
<div key="c">c</div>
</GridLayout>
);
}
}You may also choose to set layout properties directly on the children:
import GridLayout from "react-grid-layout";
class MyFirstGrid extends React.Component {
render() {
return (
<GridLayout className="layout" cols={12} rowHeight={30} width={1200}>
<div key="a" data-grid={{ x: 0, y: 0, w: 1, h: 2, static: true }}>
a
</div>
<div key="b" data-grid={{ x: 1, y: 0, w: 3, h: 2, minW: 2, maxW: 4 }}>
b
</div>
<div key="c" data-grid={{ x: 4, y: 0, w: 1, h: 2 }}>
c
</div>
</GridLayout>
);
}
}A module usable in a <script> tag is included here. It uses a UMD shim and
excludes React, so it must be otherwise available in your application, either via RequireJS or on window.React.
To make RGL responsive, use the <ResponsiveReactGridLayout> element:
import { Responsive as ResponsiveGridLayout } from "react-grid-layout";
class MyResponsiveGrid extends React.Component {
render() {
// {lg: layout1, md: layout2, ...}
const layouts = getLayoutsFromSomewhere();
return (
<ResponsiveGridLayout
className="layout"
layouts={layouts}
breakpoints={{ lg: 1200, md: 996, sm: 768, xs: 480, xxs: 0 }}
cols={{ lg: 12, md: 10, sm: 6, xs: 4, xxs: 2 }}
>
<div key="1">1</div>
<div key="2">2</div>
<div key="3">3</div>
</ResponsiveGridLayout>
);
}
}When in responsive mode, you should supply at least one breakpoint via the layouts property.
When using layouts, it is best to supply as many breakpoints as possible, especially the largest one.
If the largest is provided, RGL will attempt to interpolate the rest.
You will also need to provide a width, when using <ResponsiveReactGridLayout> it is suggested you use the HOC
WidthProvider as per the instructions below.
It is possible to supply default mappings via the data-grid property on individual
items, so that they would be taken into account within layout interpolation.
Both <ResponsiveReactGridLayout> and <ReactGridLayout> take width to calculate
positions on drag events. In simple cases a HOC WidthProvider can be used to automatically determine
width upon initialization and window resize events.
import { Responsive, WidthProvider } from "react-grid-layout";
const ResponsiveGridLayout = WidthProvider(Responsive);
class MyResponsiveGrid extends React.Component {
render() {
// {lg: layout1, md: layout2, ...}
var layouts = getLayoutsFromSomewhere();
return (
<ResponsiveGridLayout
className="layout"
layouts={layouts}
breakpoints={{ lg: 1200, md: 996, sm: 768, xs: 480, xxs: 0 }}
cols={{ lg: 12, md: 10, sm: 6, xs: 4, xxs: 2 }}
>
<div key="1">1</div>
<div key="2">2</div>
<div key="3">3</div>
</ResponsiveGridLayout>
);
}
}This allows you to easily replace WidthProvider with your own Provider HOC if you need more sophisticated logic.
WidthProvider accepts a single prop, measureBeforeMount. If true, WidthProvider will measure the
container's width before mounting children. Use this if you'd like to completely eliminate any resizing animation
on application/component mount.
Have a more complicated layout? WidthProvider is very simple and only
listens to window 'resize' events. If you need more power and flexibility, try the
SizeMe React HOC as an alternative to WidthProvider.
RGL supports the following properties (see the source for the final word on this):
//
// Basic props
//
// This allows setting the initial width on the server side.
// This is required unless using the HOC <WidthProvider> or similar
width: number,
// If true, the container height swells and contracts to fit contents
autoSize: ?boolean = true,
// Number of columns in this layout.
cols: ?number = 12,
// A CSS selector for tags that will not be draggable.
// For example: draggableCancel:'.MyNonDraggableAreaClassName'
// If you forget the leading . it will not work.
// .react-resizable-handle" is always prepended to this value.
draggableCancel: ?string = '',
// A CSS selector for tags that will act as the draggable handle.
// For example: draggableHandle:'.MyDragHandleClassName'
// If you forget the leading . it will not work.
draggableHandle: ?string = '',
// Compaction type.
compactType: ?('vertical' | 'horizontal' | null) = 'vertical';
// Layout is an array of objects with the format:
// The index into the layout must match the key used on each item component.
// If you choose to use custom keys, you can specify that key in the layout
// array objects using the `i` prop.
layout: ?Array<{i?: string, x: number, y: number, w: number, h: number}> = null, // If not provided, use data-grid props on children
// Margin between items [x, y] in px.
margin: ?[number, number] = [10, 10],
// Padding inside the container [x, y] in px
containerPadding: ?[number, number] = margin,
// Rows have a static height, but you can change this based on breakpoints
// if you like.
rowHeight: ?number = 150,

// we should set scale coefficient to avoid render artefacts while dragging.

// If set, implies `preventCollision`.

The new properties and changes are:
// {name: pxVal}, e.g. {lg: 1200, md: 996, sm: 768, xs: 480}
// Breakpoint names are arbitrary but must match in the cols and layouts objects.
breakpoints: ?Object = {lg: 1200, md: 996, sm: 768, xs: 480, xxs: 0},
// # of cols. This is a breakpoint -> cols map, e.g. {lg: 12, md: 10, ...}
cols: ?Object = {lg: 12, md: 10, sm: 6, xs: 4, xxs: 2},
// margin (in pixels). Can be specified either as horizontal and vertical margin, e.g. `[10, 10]` or as a breakpoint -> margin map, e.g. `{lg: [10, 10], md: [10, 10], ...}.
margin: [number, number] | {[breakpoint: $Keys<breakpoints>]: [number, number]},
// containerPadding (in pixels). Can be specified either as horizontal and vertical padding, e.g. `[10, 10]` or as a breakpoint -> containerPadding map, e.g. `{lg: [10, 10], md: [10, 10], ...}.
containerPadding: [number, number] | {[breakpoint: $Keys<breakpoints>]: [number, number]},
// layouts is an object mapping breakpoints to layouts.
// e.g. {lg: Layout, md: Layout, ...}
layouts: {[key: $Keys<breakpoints>]: Layout},
//
// Callbacks
//
// Calls back with breakpoint and new # cols
onBreakpointChange: (newBreakpoint: string, newCols: number) => void,
// Callback so you can save the layout.
// AllLayouts are keyed by breakpoint.
onLayoutChange: (currentLayout: Layout, allLayouts: {[key: $Keys<breakpoints>]: Layout}) => void,
// Callback when the width changes, so you can modify the layout as needed.
onWidthChange: (containerWidth: number, margin: [number, number], cols: number, containerPadding: [number, number]) => void;RGL supports the following properties on grid items or layout items. When initializing a grid,
build a layout array (as in the first example above), or attach this object as the data-grid property
to each of your child elements (as in the second example).
If data-grid is provided on an item, it will take precedence over an item in the layout with the same key (i).
Note that if a grid item is provided but incomplete (missing one of x, y, w, or h), an error
will be thrown so you can correct your layout.
If no properties are provided for a grid item, one will be generated with a width and height of 1.
You can set minimums and maximums for each dimension. This is for resizing; it of course has no effect if resizing is disabled. Errors will be thrown if your mins and maxes overlap incorrectly, or your initial dimensions are out of range.
Any <GridItem> properties defined directly will take precedence over globally-set options. For
example, if the layout has the property isDraggable: false, but the grid item has the prop isDraggable: true, the item
will be draggable, even if the item is marked static: true.
{
// A string corresponding to the component key
i: string,
// These are all in grid units, not pixels
x: number,
y: number,
w: number,
h: number,
minW: ?number = 0,
maxW: ?number = Infinity,
minH: ?number = 0,
maxH: ?number = Infinity,
// If true, equal to `isDraggable: false, isResizable: false`.
static: ?boolean = false,
// If false, will not be draggable. Overrides `static`.
isDraggable: ?boolean = true,
// If false, will not be resizable. Overrides `static`.
isResizable: ?boolean = true,
// By default, a handle is only shown on the bottom-right (southeast) corner.
// As of RGL >= 1.4.0, resizing on any corner works just fine!
resizeHandles?: ?Array<'s' | 'w' | 'e' | 'n' | 'sw' | 'nw' | 'se' | 'ne'> = ['se']
// If true and draggable, item will be moved only within grid.
isBounded: ?boolean = false
}Grid item widths are based on container and number of columns. The size of a grid unit's height is based on rowHeight.
Note that an item that has h=2 is not exactly twice as tall as one with h=1 unless you have no margin!
In order for the grid to not be ragged, when an item spans grid units, it must also span margins. So you must add the height or width or the margin you are spanning for each unit. So actual pixel height is (rowHeight * h) + (marginH * (h - 1).
For example, with rowHeight=30, margin=[10,10] and a unit with height 4, the calculation is (30 * 4) + (10 * 3)
If this is a problem for you, set margin=[0,0] and handle visual spacing between your elements inside the elements' content.
<ReactGridLayout> has an optimized shouldComponentUpdate implementation, but it relies on the user memoizing the children array:
// lib/ReactGridLayout.jsx
// ...
shouldComponentUpdate(nextProps: Props, nextState: State) {
return (
// NOTE: this is almost always unequal. Therefore the only way to get better performance
// from SCU is if the user intentionally memoizes children. If they do, and they can
// handle changes properly, performance will increase.
this.props.children !== nextProps.children ||
!fastRGLPropsEqual(this.props, nextProps, isEqual) ||
!isEqual(this.state.activeDrag, nextState.activeDrag)
);
}
// ...If you memoize your children, you can take advantage of this, and reap faster rerenders. For example:
function MyGrid(props) {
const children = React.useMemo(() => {
return new Array(props.count).fill(undefined).map((val, idx) => {
return <div key={idx} data-grid={{ x: idx, y: 1, w: 1, h: 1 }} />;
});
}, [props.count]);
return <ReactGridLayout cols={12}>{children}</ReactGridLayout>;
}Because the children prop doesn't change between rerenders, updates to <MyGrid> won't result in new renders, improving performance.
Using hooks to save your layout state on change will cause the layouts to re-render as the ResponsiveGridLayout will change it's value on every render. To avoid this you should wrap your WidthProvider in a useMemo:
const ResponsiveReactGridLayout = useMemo(() => WidthProvider(Responsive), []);If you use React Components as grid children, they need to do a few things:
- Forward refs to an underlying DOM node, and
- Forward
style,className,onMouseDown,onMouseUpandonTouchEndto that same DOM node.
For example:
const CustomGridItemComponent = React.forwardRef(({style, className, onMouseDown, onMouseUp, onTouchEnd, children, ...props}, ref) => {
return (
<div style={{ /* styles */, ...style}} className={className} ref={ref} onMouseDown={onMouseDown} onMouseUp={onMouseUp} onTouchEnd={onTouchEnd}>
{/* Some other content */}
{children} {/* Make sure to include children to add resizable handle */}
</div>
);
})The same is true of custom elements as draggable handles using the draggableHandle prop. This is so that
the underlying react-draggable library can get a reference to the DOM node underneath, manipulate
positioning via style, and set classes.
