Answer 1

In addition to the solution of Klaster_1, add an extra parameter to make the filter more generic:

Implementation

Filter

.filter('orderEmpty', function () {
    return function (array, key, type) {
        var present, empty, result;

        if(!angular.isArray(array)) return;

        present = array.filter(function (item) {
            return item[key];
        });

        empty = array.filter(function (item) {
            return !item[key]
        });

        switch(type) {
            case 'toBottom':
                result = present.concat(empty);
                break;
            case 'toTop':
                result = empty.concat(present);
                break;

                // ... etc, etc ...

            default:
                result = array;
                break;
        }
        return result;
    };
});

Thnx Klaster_1!
