Using npm:

$ npm install gridstack

You can download files from dist directory as well.

Basic usage

<div class="grid-stack">
    <div class="grid-stack-item"
        data-gs-x="0" data-gs-y="0"
        data-gs-width="4" data-gs-height="2">
            <div class="grid-stack-item-content"></div>
    </div>
    <div class="grid-stack-item"
        data-gs-x="4" data-gs-y="0"
        data-gs-width="4" data-gs-height="4">
            <div class="grid-stack-item-content"></div>
    </div>
</div>

<script type="text/javascript">
$(function () {
    $('.grid-stack').gridstack();
});
</script>

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 was 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.

API Documentation

Documentation can be found here.

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

gridstack.js for specific frameworks

Change grid width

To change grid width (columns count), to addition to width option, CSS rules for .grid-stack-item[data-gs-width="X"] and .grid-stack-item[data-gs-x="X"] have to be changed accordingly.

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.

Here is a SASS code snippet which can make life easier (Thanks to @ascendantofrain, #81 and @StefanM98, #868):

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

    $gridstack-columns: 12;

    @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; }
    }
}

Or you can include gridstack-extra.css. See below for more details.

Extra CSS

There are few extra CSS batteries in gridstack-extra.css (gridstack-extra.min.css).

Different grid widths

You can use other than 12 grid width:

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

$('.grid-stack').gridstack({width: N});

See example: 2 grids demo

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.

IE8 support

Support of IE8 is quite limited and is not a goal at this time. As far as IE8 doesn't support DOM Level 2 I cannot manipulate with CSS stylesheet dynamically. As a workaround you can do the following:

Create gridstack-ie8.css for your configuration (sample for grid with cell height of 60px can be found here).
Include this CSS:

<!--[if lt IE 9]>
<link rel="stylesheet" href="gridstack-ie8.css"/>
<![endif]-->

You can use this python script to generate such kind of CSS:

#!/usr/bin/env python

height = 60
margin = 20
N = 100

print '.grid-stack > .grid-stack-item { min-height: %(height)spx }' % {'height': height}

for i in range(N):
	h = height * (i + 1) + margin * i
	print '.grid-stack > .grid-stack-item[data-gs-height="%(index)s"] { height: %(height)spx }' % {'index': i + 1, 'height': h}

for i in range(N):
	h = height * (i + 1) + margin * i
	print '.grid-stack > .grid-stack-item[data-gs-min-height="%(index)s"] { min-height: %(height)spx }' % {'index': i + 1, 'height': h}

for i in range(N):
	h = height * (i + 1) + margin * i
	print '.grid-stack > .grid-stack-item[data-gs-max-height="%(index)s"] { max-height: %(height)spx }' % {'index': i + 1, 'height': h}

for i in range(N):
	h = height * i + margin * i
	print '.grid-stack > .grid-stack-item[data-gs-y="%(index)s"] { top: %(height)spx }' % {'index': i , 'height': h}

There are at least two more issues with gridstack in IE8 with jQueryUI resizable (it seems it doesn't work) and droppable. If you have any suggestions about support of IE8 you are welcome here: gridstack#76

Use with require.js

If you're using require.js and a single file jQueryUI please check out this Stackoverflow question to get it working properly.
