I Have 2 differents AngularJs modules : a widgetContainer and a widget.

A widget can be displayed as an independant application or be included into a widgetContainer. A widgetContainer contains 0-N widgets.

If i try to boostrap the widget module into the widgetContainer, angular throw the following error :

Error: [ng:btstrpd] App already bootstrapped with this element '<div id="childApp">' http://errors.angularjs.org/1.5.8/ng/btstrpd?p0=%26lt%3Bdiv%20id%3D%22childApp%22%26gt%3B

I have reproduce this error in this plunk

<div id="parentApp"> <div ng-controller="MainParentCtrl"> Hello {{name}} ! <div id="childApp"> <div ng-controller="MainChildCtrl"> Hello {{childName}} ! </div> </div> </div>

EDIT :

Using Dependency injection solve the problem efficiently.

Now, I need to load the widget from a directive.

parentApp.directive('widget', [function() { return { restrict: 'E', link: function($scope, $element, $attr) { var div = document.createElement('div'); div.setAttribute("ng-controller", "MainChildCtrl"); div.innerHTML = 'Hello {{childName}} !'; $element.append(angular.element(div)); } }; }]);

The div is created but the childApp module is not loaded inside. I have updated my plunker

To achieve expected result, use below

angular.element(document).ready(function() { angular.bootstrap(document.getElementById('parentApp'), ['parentApp','childApp']); });

Syntax for manual bootstrap is as below irrespective of usage of controllers on elements

angular.bootstrap(element, [modules]);
