Mobile-friendly Javascript library for dashboard layout and creation. Making a drag-and-drop, multi-column dashboard has never been easier. Allows you to build draggable, responsive bootstrap v3-friendly layouts. It also has multiple bindings and works great with React, Angular, Knockout.js, Ember and others, and comes with a Typescript definition out of the box.

Inspired by no-longer maintained gridster.js, built with love.

Basic usage

<div class="grid-stack">
  <div class="grid-stack-item">
    <div class="grid-stack-item-content">Item 1</div>
  </div>
  <div class="grid-stack-item" data-gs-width="2">

<script type="text/javascript">
$(function () {

see jsfiddle sample as running example too.

Requirements

  • jQuery (>= 1.8)
  • Array.prototype.find, and Number.isNaN() for IE and older browsers.
    • Note: as of v0.5.4 We supply a separate gridstack-poly.js for that (part of gridstack.all.js) or you can look at other pollyfills (core.js and mozilla.org).

Using gridstack.js with jQuery UI

  • jQuery UI (>= 1.12.0). Minimum required components: Draggable, Droppable, Resizable (Widget, Mouse, core).
    • Note: as of v0.5.4 we include this subset as jquery-ui.js (and min.js) which is part of gridstack.all.js. If you wish to bring your own lib, include the individual gridstack parts instead of all.js
  • (Optional) jquery-ui-touch-punch for touch-based devices support

API Documentation

Documentation can be found here.

Extend Library

You can easily extend or patch gridstack with code like this:

$(function () {
  // extend gridstack with our own custom method
  window.GridStackUI.prototype.printCount = function() {
    console.log('grid has ' + this.grid.nodes.length + ' items');
  };

  $('.grid-stack').gridstack();

  // you can now call on any grid this...
  $('.grid-stack').data('gridstack').printCount();
});

Touch devices support

Please use jQuery UI Touch Punch to make jQuery UI Draggable/Resizable working on touch-based devices.

<script src="core-js/client/shim.min.js"></script>
<script src="jquery.min.js"></script>
<script src="jquery-ui.min.js"></script>
<script src="jquery.ui.touch-punch.min.js"></script>

<script src="gridstack.js"></script>

Also alwaysShowResizeHandle option may be useful:

$(function () {
  var options = {
    alwaysShowResizeHandle: /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent)
  };
  $('.grid-stack').gridstack(options);
});

If you're still experiencing issues on touch devices please check #444

Change grid columns

GridStack makes it very easy if you need [1-12] columns out of the box (default is 12), but you always need 2 things if you need to customize this:

  1. Change the column grid option when creating a grid to your number N
$('.grid-stack').gridstack( {column: N} );
  1. include gridstack-extra.css if N < 12 (else custom CSS - see next). Without these, things will not render/work correctly.
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/gridstack@0.6.4/dist/gridstack-extra.css"/>

<div class="grid-stack grid-stack-N">...</div>

Note: we added grid-stack-N class and gridstack-extra.css which defines CSS for grids with custom [1-12] columns. Anything more and you'll need to generate the SASS/CSS yourself (see next).

See example: 2 grids demo with 6 columns

Custom columns CSS

If you need > 12 columns or want to generate the CSS manually you will need to generate CSS rules for .grid-stack-item[data-gs-width="X"] and .grid-stack-item[data-gs-x="X"].

For instance for 3-column grid you need to rewrite CSS to be:

.grid-stack-item[data-gs-width="3"]  { width: 100% }
.grid-stack-item[data-gs-width="2"]  { width: 66.66666667% }
.grid-stack-item[data-gs-width="1"]  { width: 33.33333333% }

.grid-stack-item[data-gs-x="2"]  { left: 66.66666667% }
.grid-stack-item[data-gs-x="1"]  { left: 33.33333333% }

For 4-column grid it should be:

.grid-stack-item[data-gs-width="4"]  { width: 100% }
.grid-stack-item[data-gs-width="3"]  { width: 75% }
.grid-stack-item[data-gs-width="2"]  { width: 50% }
.grid-stack-item[data-gs-width="1"]  { width: 25% }

.grid-stack-item[data-gs-x="3"]  { left: 75% }
.grid-stack-item[data-gs-x="2"]  { left: 50% }
.grid-stack-item[data-gs-x="1"]  { left: 25% }

and so on.

Better yet, here is a SASS code snippet which can make life much easier (Thanks to @ascendantofrain, #81 and @StefanM98, #868) and you can use sites like sassmeister.com to generate the CSS for you instead:

.grid-stack > .grid-stack-item {

  $gridstack-columns: 12;

  min-width: (100% / $gridstack-columns);

  @for $i from 1 through $gridstack-columns {
    &[data-gs-width='#{$i}'] { width: (100% / $gridstack-columns) * $i; }
    &[data-gs-x='#{$i}'] { left: (100% / $gridstack-columns) * $i; }
    &[data-gs-min-width='#{$i}'] { min-width: (100% / $gridstack-columns) * $i; }
    &[data-gs-max-width='#{$i}'] { max-width: (100% / $gridstack-columns) * $i; }
  }
}

you can also look at the SASS src/gridstack-extra.scss and modify to add more columns and also have the .grid-stack-N prefix to support letting the user change columns dynamically.

Override resizable/draggable options

You can override default resizable/draggable options. For instance to enable other then bottom right resizing handle you can init gridstack like:

$('.grid-stack').gridstack({
  resizable: {
    handles: 'e, se, s, sw, w'
  }
});

Note: It's not recommended to enable nw, n, ne resizing handles. Their behaviour may be unexpected.

Migrating to v0.3.0

As of v0.3.0, gridstack introduces a new plugin system. The drag'n'drop functionality has been modified to take advantage of this system. Because of this, and to avoid dependency on core code from jQuery UI, the plugin functionality was moved to a separate file.

To ensure gridstack continues to work, either include the additional gridstack.jQueryUI.js file into your HTML or use gridstack.all.js:

<script src="gridstack.js"></script>
<script src="gridstack.jQueryUI.js"></script>

or

<script src="gridstack.all.js"></script>

We're working on implementing support for other drag'n'drop libraries through the new plugin system.
