Hi I would like to display dynamically the drop down of the id and name in angular JS. Please let me know how here is the code.

// In the controller SafetyAuditController
  @RemoteAction
    global static string searchProject(string sSiteId){
        
       // id myId1 = UserInfor.getUserId();
       // system.debug(myId1);
        
        Site__c Site1 = [Select Id, Name , Project__c, Project__r.Name,Site_Master__r.Name, Site_Master__r.Id From Site__c where Site_Master__r.Id = :sSiteId LIMIT 4];
            
        
        
            
      
        return Site1.Project__r.Name; // here I am only displaying the name I must also                                                                     // display the id.
        
    }
// In the angular Javascript 
// the app.service
 this.SearchProject = function(siteId){
            var deferred = $q.defer();

            
            Visualforce.remoting.Manager.invokeAction('SafetyAuditController.searchProject', siteId, function(retVal, e) {   
                $rootScope.$apply(function() {
                    deferred.resolve(retVal.lSite[0]);
                });
            }, {escape:true} );

            return deferred.promise;
        };
//the function  search Project

 var promiseProjects = SiteSvc.searchProject($scope.siteId);
        promiseProjects.then( function (retVal){
            
            console.log(retVal);
            $scope.searchProj =[ { name : retval} ]
            
        });

// on the Visualforce page, which I should also display the id
  <div ng-controller = "Ctrl_SafetyAuditSection">
                
               <p>
                    You have selected:{{searchProj}}
               </p>
               <div dropdown-select = "searchProj"
                    dropdown-model="searchProj"
                    dropdown-item-label="text">
                   
               </div>
        </div>

the Site Master object is the lookup relationship with the site object hence I need to fetch the site master id to process the query.

thanks
