These two directives individually are pretty awesome, but they also go together really well, at least for demonstrating features. ngList converts string lists into arrays, while ngPluralize converts arrays into different strings based on the item count in the list. Both are important to know.
In the blog post Considering Speed and Slowness in AngularJS, the idea is put forward to use MustacheJS, wrapped in an AngularJS Directive to render dynamic content, but come away with no or minimal bindings. I liked the idea, but I found the application too specific; while I get the philosophy of making Directives specific usage, I also hate redundant tools and making a separate directive for each and every place I want to use a Mustache template seems terrible too.
The key detail to note in this example is that the first element wrapped by my directive is a div with a ng-non-bindable on it. That is necessary to keep AngularJS from trying to parse and bind your Mustache template code.
Ok, so this is the final variation on this that I'm going to post, even though I know that there are more efficient ways to handle element creation in AngularJS than using the ngIf block I'm using here. I've update the previous examples so that we now have two types of rendering for form questions, and the values are still tied to the underlying options values.
So this is the update to the earlier example, ditching the directive in favor of just simple Angular templating with ngOption and ngRepeat. The point here is to change both the UI and the object being acted upon in a very simple way: Use one dynamic data-set to control another dynamic data-set.
A neat bit of Mustache implementation that I'd not really used before but needed: Mustache allows you to access higher contexts by reference, as long as there is not a conflict. A very clean solution unless you have values with a conflicting names, in which case the current context takes precedence.
This is a variation on a previous example, but I was recently asked how to generate HTML for tested items with AngularJS. This process is simple: create a fragment that represents the repeating element and then use ng-include and careful reference naming to create the recursion.
