gridstack.js is a jQuery plugin for widget layout
npm install wobal-gridstackgridstack.js
============





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.

Demo
====
Please visit http://troolee.github.io/gridstack.js/ for demo. Or check out these example.
Usage
=====
* lodash.js (>= 3.5.0, full build)
* jQuery (>= 3.1.0)
Note: You can still use underscore.js (>= 1.7.0) instead of lodash.js
#### Using gridstack.js with jQuery UI
* jQuery UI (>= 1.12.0). Minimum required components: Core, Widget, Mouse, Draggable, Resizable
* (Optional) jquery-ui-touch-punch for touch-based devices support
``html`
* Using CDN:
`html`
* Using bower:
`bash`
$ bower install gridstack
* Using npm:

`bash`
$ npm install gridstack
You can download files from dist directory as well.
`html
data-gs-x="0" data-gs-y="0"
data-gs-width="4" data-gs-height="2">
data-gs-x="4" data-gs-y="0"
data-gs-width="4" data-gs-height="4">
`
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:
`html`
or
`html`
We're working on implementing support for other drag'n'drop libraries through the new plugin system.
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 feel free to as a questions here in issues, using Stackoverflow or Slack chat.
We will glad to answer and help you as soon as we can.
Also please check our FAQ doc/FAQ.md before asking in case the answer is already there.
Please use jQuery UI Touch Punch to make jQuery UI Draggable/Resizable
working on touch-based devices.
`html
`
Also alwaysShowResizeHandle option may be useful:
`javascript`
$(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
`javascript
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:
[
'
$(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:
`html`
See examples: example 1, example 2.
Notes: It's very important to exclude training spaces after widget template:
`javascript
template:
[
'',
' ',', // <-- NO SPACE AFTER
' ....',
'
'
Otherwise
addDisposeCallback won't work.
Use with angular.js
Please check gridstack-angular
Rails integration
For rails users, integration of gridstack.js and its dependencies can be done through gridstack-js-rails
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:
`css
.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:
`css
.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):
`sass
.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.Extra CSS
There are few extra CSS batteries in
gridstack-extra.css (gridstack-extra.min.css).$3
You can use other than 12 grid width:
`html
...
`
`javascript
$('.grid-stack').gridstack({width: N});
`See example: 2 grids demo
Save grid to array
Because gridstack doesn't track any kind of user-defined widget id there is no reason to make serialization to be part
of gridstack API. To serialize grid you can simply do something like this (let's say you store widget id inside
data-custom-id
attribute):`javascript
var res = _.map($('.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.Load grid from array
`javascript
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 = $('.grid-stack').data('gridstack');
grid.removeAll();
_.each(serialization, function (node) {
grid.addWidget($('
'),
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.
Override resizable/draggable options
You can override default
resizable/draggable options. For instance to enable other then bottom right resizing handle
you can init gridsack like:`javascript
$('.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:`html
`- You can use this python script to generate such kind of CSS:
`python
#!/usr/bin/env pythonheight = 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: https://github.com/troolee/gridstack.js/issues/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.
Nested grids
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 active grid
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
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
