This directive allows you to sort an array with drag & drop.
All the jQueryUI Sortable options can be defined in your controller.
plugin.controller('MyController', function($scope) {
    $scope.items = ["One", "Two", "Three"];
    $scope.sortableOptions = {
        update: function(e, ui) { ... },
        axis: 'x'
    };
});Apply the directive to your form elements:
<ul ui-sortable="sortableOptions" ng-model="items">
    <li ng-repeat="item in items"></li>
</ul>
