- directive in module ngMessages
ngMessages is a directive that is designed to show and hide messages based on the state of a key/value object that it listens on. The directive itself compliments error message reporting with the ngModel $error object (which stores a key/value state of validation errors).
ngMessages manages the state of internal messages within its container element. The internal messages use the ngMessage directive and will be inserted/removed from the page depending on if they're present within the key/value object. By default, only one message will be displayed at a time and this depends on the prioritization of the messages within the template. (This can be changed by using the ng-messages-multiple on the directive container.)
A remote template can also be used to promote message reusability and messages can also be overridden.
