Include 'angular-gridster2' as a dependency of your module like this:

  var module = angular.module("app", ["angular-gridster2"]);

Usage

Default usage:

<gridster options="vm.options">
  <gridster-item item="item" ng-repeat="item in vm.dashboard"></gridster-item>
</gridster>

Initialize a simple dashboard:

var vm = this;

vm.options = {
   gridType: 'fit',
   itemChangeCallback: itemChange,
   margin: 10,
   outerMargin: true,
   draggable: {
     enabled: true,
     stop: eventStop
   },
   resizable: {
     enabled: true,
     stop: eventStop
   }
 };

vm.dashboard = [
  {cols: 2, rows: 1, y: 0, x: 0},
  {cols: 2, rows: 2, y: 0, x: 2}
];

Note: The gridster will take all the available space from the parent. It will not size depending on content. The parent of the component needs to have a size.

Default Grid Options:

var GridsterConfigService = {
  gridType: 'fit', // 'fit' will fit the items in the container without scroll;
  // 'scrollVertical' will fit on width and height of the items will be the same as the width
  // 'scrollHorizontal' will fit on height and width of the items will be the same as the height
  // 'fixed' will set the rows and columns dimensions based on fixedColWidth and fixedRowHeight options
  // 'verticalFixed' will set the rows to fixedRowHeight and columns width will fit the space available
  // 'horizontalFixed' will set the columns to fixedColWidth and rows height will fit the space available
  fixedColWidth: 250, // fixed col width for gridType: 'fixed'
  fixedRowHeight: 250, // fixed row height for gridType: 'fixed'

Gridster options api

    this.options.api.resize(); // call if size of container changes. Grid will auto resize on window resize.
    this.options.api.optionsChanged(); // call on change of options after initialization
    this.options.api.getNextPossiblePosition(item: GridsterItem); // call to get a viable position for item. Returns true if found

// if you want to push items from code use the GridsterPush service
import {GridsterItemComponent, GridsterPush, GridsterPushResize, GridsterSwap} from 'gridster'

myMethod(gridsterItemComponent: GridsterItemComponent) {
  const push = new GridsterPush(gridsterItemComponent); // init the service
  gridsterItemComponent.$item.rows += 1; // move your item
  push.pushItems(push.fromEast);  // push items from a direction
  push.setPushedItems(); // save the items pushed
  push.restoreItems(); // restore to initial state the pushed items
  push.checkPushBack(); // check for items restore to original position
  
  // same for GridsterPushResize and GridsterSwap
}

Gridster item options:

export interface GridsterItem {
  x?: number; // x position if missing will auto position
  y?: number; // y position if missing will auto position
  rows?: number; // number of rows if missing will use grid option defaultItemRows
  cols?: number; // number of columns if missing will use grid option defaultItemCols
  initCallback?: Function; // initialization callback. Argument: GridsterItem, GridsterItemComponent
  dragEnabled?: boolean; // override grid option draggable.enabled
  resizeEnabled?: boolean; // override grid option resizable.enabled
  compactEnabled?: boolean; // disable compact
  maxItemRows?: number; // override grid option maxItemRows
  minItemRows?: number; // override grid option minItemRows
  maxItemCols?: number; // override grid option maxItemCols
  minItemCols?: number; // override grid option minItemCols
  minItemArea?: number; //  override grid option minItemArea
  maxItemArea?: number; //  override grid option maxItemArea
}

Gridster Item Events

broadcasts 'gridster-item-change' // triggered when a item cols,rows, x ,y changed

broadcasts 'gridster-item-resize' // triggered when a item width/height changed

Note: When a item changes cols/rows both events get triggered

Via Constant

You can also override the default configuration by modifying the gridsterConfig constant

angular.module('app').run(['gridsterConfig', function(GridsterConfig) {
	 GridsterConfig.gridType = 'fit';
}]);
