Installation

Install the React-Grid-Layout package package using npm:

npm install react-grid-layout

Include the following stylesheets in your application:

              /node_modules/react-grid-layout/css/styles.css /node_modules/react-resizable/css/styles.css                          

Usage

Use ReactGridLayout like any other component. The post-obit instance below will produce a grid with 3 items where:

• users will not exist able to drag or resize item a
• item b will be restricted to a minimum width of two 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-filigree-layout'                ;                class                MyFirstGrid                extends                React                .

• Tracking `adjacent` release

  As many have you been awaiting, the next branch:

  • Contains a refactor of most of the projection
  • Has React 0.14 Support
  • Has ameliorate IE/Touch compatibility
  • Is fully validated using Catamenia
  • Uses mainline React-Draggable and React-Resizable (1.x versions).

  Much of the difficulty in this co-operative involves a rethinking of how we manage country in child components and a move toward a completely stateless <Draggable>, which is not withal integrated in RGL.

  This effect is tracking the release of this branch. Meet besides discussion in #117.

  Blockers:

  • [10] React-Draggable 1.x is calling back with clientX/Y when it should be sending offsetX/Y. This is causing a bad 300px offset in the demo. (fixed in https://github.com/mzabriskie/react-draggable/commit/c1a5bb3daaebfef07512fabf9dfbd435279241c8)
  • [x] Draggable is non post-obit mouse position with placeholder in the filigree, it is instead following the placeholder directly. For example:
  • [ten] Apply <DraggableCore> directly and store state in RGL, rather than in each <Draggable>.

  Stretch goals:

  • [ ] Once onto <DraggableCore>, we can use percentage top/left and height/width direct. This volition non only allow us to stop listening for resize events, but do more proper server-side rendering.
    • Tin we nonetheless use CSS transforms with percentages? CSS transform percentages are relative to the element's width/summit, not the offsetParent's width/height. We could trick it past measuring the offsetParent and doing the math with JS, but we lose the server-rendering benefits as above.

• Child component does not properly inherit GridItem props

  Hi, I am rather new to React as a whole, so if this result is off-base or needs clarification please don't hesitate.

  I am seeing an issue where I define a child component and endeavour to instantiate it through the standard React constructor as seen beneath. "tile_info" is an object retrieved from a server which you can assume contains attributes seen in TilePanel

                                <ReactGridLayout ref="rgl" {...this.props} layout={this.props.layout}>     <TilePanel tile={this.props.tile_info} grid={this.generateGrid()} </ReactGridLayout>                                                          

                                var TilePanel = React.createClass({   render: function () {     return (         <div key={this.props.tile.championship} form="widget-number" data-grid ={this.props.filigree} >           <h1 className="title">{this.props.tile.championship}</h1>           <h2 className="value">{this.props.tile.value}</h2>           <p style={styles.last_updated}>{this.props.tile.last_update}</p>         </div>     )   } });                                                          

  The resulting HTML for that GridItem does not contain the expected class/fashion attributes.
  Expected:

                                <div class="react-grid-item widget-number     cssTransforms react-resizable" style="width: 270px; height: 310px; position: absolute; bear on-action: none; transform: interpret(10px, 10px);">                                                          

  Actual:

                                <div form="widget-number" manner="background-colour:#ff9618;" data-reactid=".0.1.0.1.0:$/=one$daily_revenue">                                                          

  Notice the lack of props on the grade and way attributes.

  If this isn't clear, I will do my best to clarify

• Grid item class name not changing

  I'm running into an upshot dynamically updating the classname of a filigree item.

  I have a button that adds an item to the grid when clicked. When the item is created, I add actress props such equally boolean for if it's a new item, a class name to specify that it is true for styling, and a boolean setting edit manner to true. When the item is confirmed, a push button click there is meant to update the item setting the booleans to false and irresolute the class name. The class proper name on the element stays the same, though. I'yard assuming this is because on updates simply layout data is cared nearly.

  Is at that place any style I can make this piece of work?

• How should the parent pass in new layout(due south)?

  Related to #98

  This is an open consequence for annotate.

  Currently, the following methods are used to determine whether or not to reload the layout:

  RGL:

  !_.isEqual(this.props.layout, nextProps.layout)

  ResponsiveRGL:

  ``!_.isEqual(this.props.layouts, nextProps.layouts)`

  This doesn't fairly cover some apply issues, like:

  • (#98) - If I reset the layout, to what was originally passed in, the props haven't changed, so the layout doesn't reset.

  This is really very similar to the problem that acquired me to rewrite <Draggable> in the starting time place. It's difficult, in React, to enforce a state reset on children at some times while assuasive them to manage their own country at other times.

  Should users just only take hold of a ref and setState() themselves? I don't know if I see a ameliorate option.

• Looking for Maintainers

  Devs,

  As is likely obvious at this betoken, I don't accept the time to go along up with the big influx of issues on this repository. RGL works great for our use example at BitMEX but is clearly not as customizable every bit the community wants it to be.

  My intention is for RGL to ascertain proper extension points so that a vibrant plugin system may emerge, reducing the brunt on this repository to implement custom functionality, such every bit compactors. For those reasons, I've prepared #346 which defines this in particular.

  Are in that location whatsoever volunteers to help go the work started? I would be happy to review PRs but I simply don't take the time to spearhead this.

• AutoSize not working on initial ResponsiveReactGridLayout render

  Hi. I'thousand non sure if I'm doing something wrong simply it seems similar ResponsiveReactGridLayout autoSize doesn't burn initially, or not after the initial rendering. In the attached gif I show reloading the page, the filigree width is fully sized based on the widget layout but its not resized.

  When I resize the browser window the grid volition automobile resize, but when I reload the page, aforementioned story.

  

  My usage is as follows. The trouble exists with or without the onBreapointChange scrap that I had to add together to force pre-render on breakpoint changes related to another outcome.

  I played with the layout change callback and they don't fire on initial render. Whatever tips would be bang-up. Cheers.

• ResponsiveReactGridLayout breakpoint resizing doesn't pop dorsum when growing to original size

  Hi. When using ResponsiveReactGridLayout it appears as if when I compress the viewport the breakpoints are enforced and the grid layout pops downwardly accordingly, simply when I grow it back through larger breakpoints, I see the items resize but and then shrink downwards once again. This could be some misuse of the breakpoint sizes in relation to the item sizes. I'm not sure. Any guidance would exist awesome.

  I was using RGL 1.0.0 but I updated to 1.3.3 merely now and the trouble notwithstanding persists.

  Hither'due south a captured video of the problem

  

  Here'due south some bits from my lawmaking, hopefully its enough to spot if this is a bug or a user error:

                                const widgets = [   {     id: 'IncrementWidget',     layout: { i: 'IncrementWidget', x: 0, y: 0, w: i, h: ii, isDraggable: false },   },   {     id: 'DecrementWidget',     layout: { i: 'DecrementWidget', 10: 1, y: 0, due west: 1, h: ii, isDraggable: false },   },   {     id: 'ImageWidget',     layout: { i: 'ImageWidget', x: ii, y: 0, w: 1, h: i, isDraggable: false },   },   {     id: 'ImageWidget',     layout: { i: 'ImageWidget', x: 2, y: 1, w: ane, h: one, isDraggable: false },   },   {     id: 'ImageWidget',     layout: { i: 'ImageWidget', x: 3, y: 0, w: 1, h: 2, isDraggable: false },   },   {     id: 'ImageWidget',     layout: { i: 'ImageWidget', x: 0, y: 1, w: iv, h: 2, isDraggable: false },   }, ];  ...          <ResponsiveReactGridLayout             autoSize             cols={iv} // 3 chunky cols             breakpoints={{lg: 1200, md: 996, sm: 768}}             cols={{lg: 4, md: 2, sm: 1}}             preventCollision             useCSSTransforms             isDroppable             compactType={null}             rowHeight={150}             onDrop={onDrop}             onDragStop={onLayoutChange}             onResizeStop={onLayoutChange}         >           {widgets.map((ten, idx) => (             <DashboardWidget central={'widget_'+idx} widget={x} information-filigree={10.layout} />           ))}         </ResponsiveReactGridLayout>

• Crash in IE11

  Hi guys,

  https://github.com/react-grid-layout/react-filigree-layout/blob/7c06498166b3c8613c866f374da5dd318c5faa8d/lib/calculateUtils.js#L31

  The line above causes a crash in IE11 with the error Object doesn't support property or method 'isFinite'. This is the simply line in the project which uses this syntax, so maybe it would be worth using code below instead, which is supported in IE11:

                                if (!isFinite(gridUnits)) return gridUnits;
