I am using MEAN stack in my application with AngularJS as my front-end. How can i use typeahead in input filed to get the values in angularjs , actually we get the value if we using select option, but we expecting for type-ahead option ...please look into plunker for the reference My Plunker.
In plunker first select option used to get the without array values.
Second select option are used to get the value in array of user. so we used like ng-options="item.user.displayName for item in questions"
But we expecting for typeahead option to get the displayNmae values in array of user. so we used like typeahead="item as item.user.displayName for item in questions | filter:$viewValue | limitTo:8" But we could't get the answer...
what we exactly looking in third input filed if we type a name the drop down should need to display...
Please if any one knows the solution ,please update plunker as well to know the solution.
