AngularJS - Multiple select with setting default value of select dynamically

Question

Code for each product and it's catalogue information in drop down individually using AngularJS:

<ul style="height:250px;" >
<li data-ng-repeat="product in products" >
<div> {{SelectedOption.Price}} </div>
<select  data-ng-model="SelectedOption"  data-ng-init="SelectedOption=Catalogues[0]" data-ng-options="Catalogue as Catalogue.CName for Catalogue in Catalogues | filter:{ProductId:product.ProductId}:true" >                             
</select>
</li>
</ul>

Controller code is like this

 var app = angular.module('myApp', []);
 app.controller('myControl', function ($scope) {
 $scope.products = [{ productname: 'Rice1', ProductId: 1}, { productname: 'Rice2', ProductId: 2 },{ productname: 'Rice3', ProductId: 3 }];    
 $scope.Catalogues = [{ ProductId: 1, CatalogueId: 1, CName: '25KG Bag', Price: 500, sortorder: 1 }, { ProductId: 1, CatalogueId: 2, CName: '50KG Bag', Price: 1000, sortorder: 2 },{ ProductId: 2, CatalogueId: 3, CName: '100KG Bag', Price: 1800, sortorder: 2 }];

Now want to set the default value of the each product catalogue.cname dynamically with the first value of the select drop down, Any idea? Much appreciated!

To set the default value in the select, you need to set the ng-model as the first in the list you are using. Put this at the end of the controller:

 $scope.SelectedOption = $scope.Catalogues[0];

Set up a plunker, it's going to be easier to track the behavior you are expecting.

Updated plunker to question.

$scope.SelectedOption is going to be unique among all the products. You may want to create a SelectedOption property for each product: product.SelectedOption
