<script src="src/ngFlowGrid.js"></script>

2.add ngFlowGrid to your app's dependency:

var myApp = angular.module('myAppName', ['ngFlowGrid']);

3.use ngFlowGrid directive in you html code:

<ul class="flowGrid" ng-flow-grid="homePageGrid" min-item-width="200">
	<li class="flowGridItem" ng-repeat="item in items">
		<a href=""><img ng-src="{{item.img}}"></a>

4.add some basic css to format the layout

*{box-sizing: border-box;}
.flowGrid:before,.flowGrid:after{

	display: table;
}
.flowGrid:after{
	clear:both;
}
.flowGridItem{ margin-bottom:10px;}
.flowGridItem img{width:100%;}
.flowGridColumn{
	float: left;
	padding-left: 10px;
}
.flowGridColumn:last-of-type{
	padding-right: 10px;
}

5.control the grid in your controller:

app.controller('appCtrl',['$scope','fgDelegate',function($scope,fgDelegate){
	
	$scope.updateGrid = function(){
		var homePageGrid = fgDelegate.getFlow('homePageGrid');
	
		// then you can:
		homePageGrid.minItemWidth += 20;
    	homePageGrid.refill(true);
	}

}]);

take look at demo app;

#Directive options ###ngFlowGrid give a name for your grid, so that you can controll mutil grid in one page. ###itemSelector(default:'.flowGridItem') ###minItemWidth(default:150) this value will affect how many columns you have, the smaller it is the more columns there will be;

#Service through fgDelegate service you can get flow object and controll it in your controller or directive:

###new(option) options are:

• container: container element.
• name: string,the name of new grid.
• itemSelector: string
• minItemWidth: number, this will affect how many columns in grid;

###getFlow(name) this will return a flowgrid object ,and you can controll that grid throght this object

• minItemWidth:number
• container:element
• autoCalculation: boolean
• columnsHeights: array
• itemsHeights: object
• items: array of element
• refill([forceRefill]) : calculate culums based on minItemWidth,and put items into columns; [forceRefill]:boolean;
• itemsChanged(): tell flow grid you have added or removed items in your controller; before you call this method, make sure ngRepeat is finished rendering ,so you should call it like this:

 	// make sure ngRepeat is finished rendering
	$scope.$watch('$last',function(){
		fgDelegate.getFlow('demoGrid').itemsChanged();
	});

• empty() : remove all items inside of columns
