AngularJS Controllers, of lack of Controllers.

I know treehouse hasn't got any courses on AngularJS, besides that one workshop, but I'm sure a fair few folk on here have some experience with the magical framework that angular is.

I'm trying to build an interface where you can tab on different links and it shows you the corresponding info. Here's a pen of it working:

However, there is too much logic in my markup, so I need to wrap up that logic and store it in a controller. And thats exactly what I'm trying to achieve with the pen below, but with no luck!

It's frustrating when the method that's not best practice works haha. Any help would be greatly appreciated!

Cheers.

Hi. Was just looking at your code. I see the issue. It has to do with scope. You are using the new controller in the <nav> tag so it is only available to that element. A quick fix is to move the ng-controller="TabController as tab" to outer div <div class="row" ng-controller="TabController as tab"> and that should fix your problem. This allows the other elements inside that div to have access to that new controller. Really like your design in the code-pen pages clean and simple.

cheers.

Awesome. Such a rookie mistake, thanks for picking that up for me man! Makes sense that if I'm calling directives like <ul class="list-break" ng-show="tab.isSet(2)"> for the TabController that the scope needs to include all the unordered lists on the page aswell. Thanks again!

Cheers.
