How to handle recursive rendering of data using AngularJS

rather than nest your controllers, nest the data and just have the one controller.

the view is handled by a template that references itself recursively.

as chadermani has linked to, there are some answers out there.

here is a fiddle with a great example (not my code)

http://jsfiddle.net/brendanowen/uXbn6/8/

and the code from the fiddle

<script type="text/ng-template"  id="tree_item_renderer.html">
    {{data.name}}
    <button ng-click="add(data)">Add node</button>
    <button ng-click="delete(data)" ng-show="data.nodes.length > 0">Delete nodes</button>
    <ul>
        <li ng-repeat="data in data.nodes" ng-include="'tree_item_renderer.html'"></li>
    </ul>
</script>

<ul ng-app="Application" ng-controller="TreeController">
    <li ng-repeat="data in tree" ng-include="'tree_item_renderer.html'"></li>
</ul>

angular.module("myApp", []).
controller("TreeController", ['$scope', function($scope) {
    $scope.delete = function(data) {
        data.nodes = [];
    };
    $scope.add = function(data) {
        var post = data.nodes.length + 1;
        var newName = data.name + '-' + post;
        data.nodes.push({name: newName,nodes: []});
    };
    $scope.tree = [{name: "Node", nodes: []}];
}]);
