+### Inline feedback icons
+*input* and *textarea* based fields get inline status icons by default. A check
+when everything is valid and a cross when there are validation errors.
+
+This can be turned off or configured to other icons. To turn off just
+set ```feedback``` to false. If set to a string that string is evaluated by
+a ```ngClass``` in the decorators scope. If not set att all the default value
+is ```{ 'glyphicon': true, 'glyphicon-ok': hasSuccess(), 'glyphicon-remove': hasError() }```
+
+ex. displaying an asterisk on required fields
+```javascript
+  $sope.form = [
+    {
+      key: "name",
+      feedback: "{ 'glyphicon': true, 'glyphicon-asterisk': form.requires && !hasSuccess && !hassError() ,'glyphicon-ok': hasSuccess(), 'glyphicon-remove': hasError() }"
+    }
+```
+
+Useful things in the decorators scope are
+
+| Name           | Description|
+|:---------------|:----------:|
+| hasSuccess()   | *true* if field is valid and not pristine |
+| hasError()     | *true* if field is invalid and not pristine |
+| ngModel        | The controller of the ngModel directive, ex. ngModel.$valid |
+| form           | The form definition for this field |
+
