Want to make ng-repeat filter out duplicate results? You could use the unique filter from AngularUI (source code available here: AngularUI unique filter) and use it directly in the ng-options (or ng-repeat).
1 2 3 4 | <select ng-model="orderProp" ng-options="place.category for place in places | unique:'category'"> <option value="0">Default</option> // unique options from the categories </select> |
