gridstack.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

Inspired by gridster.js. Built with love.

Item attributes

• data-gs-x, data-gs-y - element position
• data-gs-width, data-gs-height - element size
• data-gs-max-width, data-gs-min-width, data-gs-max-height, data-gs-min-height - element constraints
• data-gs-no-resize - disable element resizing
• data-gs-auto-position - tells to ignore data-gs-x and data-gs-y attributes and to place element to first available position

Use with knockout.js

ko.components.register('dashboard-grid', {
    viewModel: {
        createViewModel: function (params, componentInfo) {
            var ViewModel = function (params, componentInfo) {
                var grid = null;

                this.widgets = params.widgets;

                this.afterAddWidget = function (items) {
                    _.each(items, function (item) {
                        item = $(item);

                        if (grid == null) {
                            grid = $(componentInfo.element).find('.grid-stack').gridstack({
                                auto: false
                            }).data('gridstack');
                        }

                        grid.add_widget(item);
                        ko.utils.domNodeDisposal.addDisposeCallback(item[0], function () {
                            grid.remove_widget(item);
                        });
                    }, this);
                };

            };

            return new ViewModel(params, componentInfo);
        }
    },
    template: [
        '<div class="grid-stack">',
        '   <!-- ko foreach: widgets, afterRender: afterAddWidget -->',
        '       <div class="grid-stack-item" data-bind="attr: {',
        '               \'data-gs-x\': x, \'data-gs-y\': y,',
        '               \'data-gs-width\': width, \'data-gs-height\': height}">',
        '           <span data-bind="text: $index"></span>',
        '       </div>',
        '   <!-- /ko -->',
        '</div>'
    ].join('\n')
});

and HTML:

<div data-bind="component: {name: 'dashboard-grid', params: $data}"></div>
