How to filter ng-repeat values based on another input ng-model value in angularjs?

repeat values based on another input ng-model value in angularjs?

I have one input value like Social Psychology for this value ng-model is kpcategory
I have used ng-repeat like ng-repeat="question in questions to list out the all category and name.
I tried to filter Social Psychology category in ng-repeat list, so i used like ng-repeat="question in questions | filter:kpcategory".
what the issue is, it's filtering Social Psychology data's perfectly. but i would like to filter only the category value of Social Psychology not for all data's. the issue is it's filtered includes of category and category_twodata's.

Expecting result is:-

just want to filter by catgory Social Psychology so result should be Social Psychology , John data.

Solution

You can try following to filter items by category property only

  <div ng-repeat="question in questions | filter:{ category: kpcategory }">
      <ul>
          <li><span>{{question.category}} , {{question.name}}</span></li>
      </ul>     
  </div>
