I got the following code:
<div ng-repeat="i in placeholders" square class="set-holder {{i.class}}" droppable="{{i.type}}"></div>
How I make the first item has the directive bigsquare, while the others have just square.
I've tried:
<div ng-repeat="i in placeholders" {{= $first ? 'big' : ''}}square class="set-holder {{i.class}}" droppable="{{i.type}}"></div>
but sadly I the result is:
<div ng-repeat="i in placeholders" {{= $first ? 'big' : ''}}square class="set-holder test" droppable="3"></div>
a.k.a. the binding don't get compiled.

NEST TWO ng-repeatThe first ng-repeat in the tr tag will create the rows and the second one in the td tag will create one column per element in the collection. By using one ng-repeat for the row and an other for the column, the rows and the columns of your table is now driven by a subset.
But ng-repeat is not the right thing to use when you have large datasets as it involves heavy DOM manipulations. And you should consider using ng-repeat with pagination. You can consider using transclusion inside a custom directive, to achieve the behavior you are looking for without using ng-repeat.
AngularJS ng-repeat Directive The ng-repeat directive repeats a set of HTML, a given number of times. The set of HTML will be repeated once per item in a collection. The collection must be an array or an object. Note: Each instance of the repetition is given its own scope, which consist of the current item.
Each ng-repeat creates a child scope with the passed data, and also adds an additional $index variable in that scope. So what you need to do is reach up to the parent scope, and use that $index . Save this answer.
You can use ng-repeat-start and ng-repeat-end as follows:
angular.module('example', [])
.controller('ctrl', function Ctrl($scope) {
$scope.items = [1, 2, 3];
})
.directive('big', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
element.css('font-size', '30px');
}
};
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="example" ng-controller="ctrl">
<div ng-repeat-start="item in items" ng-if="$first" big>
big item {{item}}
</div>
<div ng-repeat-end ng-if="!$first">
item {{item}}
</div>
</div>The documentation can be found under ng-repeat.
