    <p>I am building a SPA where one can open a dialog-window that contains a list of options. The user can pick an option, then said option should be attached to the main-view of the application (As in: pick <em>A</em> from a dialog, then attach <em>A</em> to an <code>&lt;ul&gt;</code> on the frontpage).</p> <p>The dialog is independet and has its own module and controller:</p> <pre><code>var AdviceList = angular.module('adviceList', []); AdviceList.controller('AdviceListCtrl',function($scope,$http){ //... }); AdviceList.provider('$adviceList',function(){ this.$get = function ($rootScope,$document,$compile,$http){ function AdviceList(){ // ... } AdviceList.prototype.open = function(){ // ... } }) </code></pre> <p>I do not understand how to share the list of chosen options with the rest of my application.</p> <p>My approach was to create an array <code>activeOptions</code> and attach it to the controller's scope, but in that case, it will be out of reach for the provider:</p> <pre><code>AdviceList.controller('AdviceListCtrl',function($scope,$http){ $scope.activeOptions = []; $scope.addAdvice = function(){ $scope.activeOptions.push(); // push the chosen option } }); AdviceList.provider('$adviceList',function(){ this.$get = function ($rootScope,$document,$compile,$http){ return{ AdviceList: function(){ return new AdviceList(); }, getActive: function(){ // no access to the controllers scope here } } } }) </code></pre> <p>What is the recommended, best practice way of sharing data application wide and implement such functionality as i need?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
