gridstack.js is a jQuery plugin for widget layout. This is drag-and-drop multi-column grid. It allows you to build draggable responsive bootstrap v3 friendly layouts. It also works great with knockout.js, angular.js and touch devices.
Inspired by gridster.js. Built with love.

As of v0.2.5 all methods and parameters are in camel case to respect JavaScript Style Guide and Coding Conventions. All old methods and parameters are marked as deprecated and still available but a warning will be displayed in js console. They will be available until v1.0 when they will be completely removed.
Please check out doc/README.md
for more information about gridstack.js API.
Please use jQuery UI Touch Punch to make jQuery UI Draggable/Resizable working on touch-based devices.

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);
});
ko.components.register('dashboard-grid', {
viewModel: {
createViewModel: function (controller, componentInfo) {
var ViewModel = function (controller, componentInfo) {
var grid = null;
this.widgets = controller.widgets;
this.afterAddWidget = function (items) {
if (grid == null) {
grid = $(componentInfo.element).find('.grid-stack').gridstack({
auto: false
}).data('gridstack');
}
var item = _.find(items, function (i) { return i.nodeType == 1 });
grid.addWidget(item);
ko.utils.domNodeDisposal.addDisposeCallback(item, function () {
grid.removeWidget(item);
});
};
};
return new ViewModel(controller, componentInfo);
}
},
template:
[
'<div class="grid-stack" data-bind="foreach: {data: widgets, afterRender: afterAddWidget}">',
' <div class="grid-stack-item" data-bind="attr: {\'data-gs-x\': $data.x, \'data-gs-y\': $data.y, \'data-gs-width\': $data.width, \'data-gs-height\': $data.height, \'data-gs-auto-position\': $data.autoPosition}">',
' <div class="grid-stack-item-content">...</div>',
' </div>',
'</div> '
].join('')
});
$(function () {
var Controller = function (widgets) {
this.widgets = ko.observableArray(widgets);
};
var widgets = [
{x: 0, y: 0, width: 2, height: 2},
{x: 2, y: 0, width: 4, height: 2},
{x: 6, y: 0, width: 2, height: 4},
{x: 1, y: 2, width: 4, height: 2}
];
ko.applyBindings(new Controller(widgets));
});
and HTML:
<div data-bind="component: {name: 'dashboard-grid', params: $data}"></div>
See examples: example 1, example 2.
Notes: It's very important to exclude training spaces after widget template:
template:
[
'<div class="grid-stack" data-bind="foreach: {data: widgets, afterRender: afterAddWidget}">',
' <div class="grid-stack-item" data-bind="attr: {\'data-gs-x\': $data.x, \'data-gs-y\': $data.y, \'data-gs-width\': $data.width, \'data-gs-height\': $data.height, \'data-gs-auto-position\': $data.autoPosition}">',
' ....',
' </div>', // <-- NO SPACE **AFTER** </div>
'</div> ' // <-- NO SPACE **BEFORE** </div>
].join('') // <-- JOIN WITH **EMPTY** STRING
Otherwise addDisposeCallback
won't work.
Please check gridstack-angular
For rails users, integration of gridstack.js and its dependencies can be done through gridstack-js-rails
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 snipped which can make life easier (Thanks to @ascendantofrain, #81):
.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) * $i; }
&.grid-stack-item[data-gs-min-width='#{$i}'] { min-width: (100% / $gridstack-columns) * $i; }
&.grid-stack-item[data-gs-max-width='#{$i}'] { max-width: (100% / $gridstack-columns) * $i; }
}
}
Or you can include gridstack-extra.css
. See below for more details.
There are few extra CSS batteries in gridstack-extra.css
(gridstack-extra.min.css
).
You can use other than 12 grid width:
<div class="grid-stack grid-stack-N">...</div>
$('.grid-stack').gridstack({width: N});
See example: 2 grids demo
Because gridstack doesn't track any kind of user-defined widget id there is no reason to make serialization to be part
of gridstack API. To serialize grid you can simply do something like this (let's say you store widget id inside data-custom-id
attribute):
var res = _.map($('.grid-stack .grid-stack-item:visible'), function (el) {
el = $(el);
var node = el.data('_gridstack_node');
return {
id: el.attr('data-custom-id'),
x: node.x,
y: node.y,
width: node.width,
height: node.height
};
});
alert(JSON.stringify(res));
See example: Serialization demo
You can also use onchange
event if you need to save only changed widgets right away they have been changed.
var serialization = [
{x: 0, y: 0, width: 2, height: 2},
{x: 3, y: 1, width: 1, height: 2},
{x: 4, y: 1, width: 1, height: 1},
{x: 2, y: 3, width: 3, height: 1},
{x: 1, y: 4, width: 1, height: 1},
{x: 1, y: 3, width: 1, height: 1},
{x: 2, y: 4, width: 1, height: 1},
{x: 2, y: 5, width: 1, height: 1}
];
serialization = GridStackUI.Utils.sort(serialization);
var grid = $('.grid-stack').data('gridstack');
grid.removeAll();
_.each(serialization, function (node) {
grid.addWidget($('<div><div class="grid-stack-item-content" /></div>'),
node.x, node.y, node.width, node.height);
});
See example: Serialization demo
If you're using knockout there is no need for such method at all.
You can override default resizable
/draggable
options. For instance to enable other then bottom right resizing handle
you can init gridsack 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.
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
If you're using require.js and a single file jQueryUI please check out this Stackoverflow question to get it working properly.
Gridstack may be nested. All nested grids have an additional class grid-stack-nested
which is assigned automatically
during initialization.
See example: Nested grid demo
Resizing on-the-fly is possible, though experimental. This may be used to make gridstack responsive. gridstack will change the total number of columns and will attempt to update the width and x values of each widget to be more logical. See example: Responsive grid demo
Using AniJS with gridstack is a breeze. In the following example, a listener is added that gets triggered by a widget being added. See widgets wiggle! AniJS demo
gridstack.js is currently maintained by Pavel Reznikov, Dylan Weiss and Kevin Dietrich. And we appreciate all contributors for help.
