Answer 1

Update your select function to set the selected property to null if it's already selected:

$scope.select = function(item) {
    $scope.selected = ($scope.selected === item ? null : item); 
};

just change your code to this:

$scope.select= function(item) {
    if (item === $scope.selected) {
        $scope.selected = null;
    } else {
        $scope.selected = item;
    }

};
