You might consider writing a directive for this. I've created a <a href="http://plnkr.co/edit/VkZaaTgWevVeyJ3UUEgN?p=preview" rel="nofollow">demo on Plunkr</a>. In the demo I have created a directive called <code>level</code> with attribute <code>value</code>. HTML which renders the list of skills with their levels is very simple: <pre><code><div ng-repeat="skill in skills"> {{ skill.desc }}: <level value="{{ skill.proficiency }}"></level> </div> </code></pre> Note that I have simplified your <code>$scope</code> a little bit for demonstration purposes (there is just the skills array, each skill has description and proficiency). Here's a directive implementation: <pre><code>app.directive('level', function() { return { restrict: 'E', link: function postLink(scope, element, attrs) { attrs.$observe('value', function(newValue) { // value attribute has changed, re-render var value = Number(newValue); element.children().remove(); while (value > 0) { element.append('x') value--; } }); } }; }); </code></pre> There are several points worth pointing out in directive implementation: <ul> <li>Directive watches the level attribute and re-renders the directive content every time the level attribute changes</li> <li>jQuery is optional and I don't use it here. Angular has its own lightweight jQuery implementation called <a href="http://code.angularjs.org/1.2.0rc1/docs/api/angular.element" rel="nofollow">jqLite</a>.</li> <li>I generate <code>x</code> for each level point to demonstrate that I can generate HTML.</li> </ul> To learn more about directives check out <a href="http://docs.angularjs.org/guide/directive" rel="nofollow">Angular's guide on directives</a>. I have also found <a href="http://www.youtube.com/watch?v=WqmeI5fZcho" rel="nofollow">Misko Hevery's talk on Directives</a> to be really useful.

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.
