http://jsfiddle.net/naxL8LvL/7/ is the directive way of doing it, though I personally dont quite like the idea of hardcoding templates inside JS or even using a templateUri.

<div ng-app="myApp">
    <div>
        <div data-mylist data-entities="[
        {firstname:'Alfred', lastname:'Hitchcock'},
        {firstname:'Emile', lastname:'Zola'}
    ]"></div>
    </div>
</div>

Open in new window


var myApp = angular.module("myApp", [])
    .directive("mylist", ['$log', function ($log) {
    return {
        restrict: "ECMA",
        replace: false,
        transclude: false,
        template: "<ul><li ng-repeat='e in entities'>{{e.lastname}}</li></ul>",
        scope: {
            'entities': '='
        }
    }
}]);

You should open a separate question for that, also because thats in itself a vast topic of discussion.

For one, a directive allows you to attach a controller and add logic there, however, you should really think in terms of data-binding and let ANGJS control most aspects of presentation. Trying to squeeze in the legacy jQuery way of imperative programming is often avoidable by the use of data-binding and directives like ng-show, ng-hide etc.
