I am new in AngularJS. In my code I have two nested ng-repeat attribute and I want to use first ng-repeat variable value to create the next ng-repeat variable. Here is my Code that not as I need.

HTML

<div ng-repeat="item in artType">    
	<select ng-model="ddlArtType">
		<option value="" disabled selected> </option>
		<option ng-repeat="selectedArtType in artCultureDependencyMap.{{item}} track by $index">
			{{selectedArtType}}
		</option>
	</select>    
</div>

Here "artType" is an array, Example value
artType=['Film', 'Music',...]
And "artCultureDependencyMap" is an object. Example value
artCultureDependencyMap['Film']=['Action','Adventure',....]
artCultureDependencyMap['Music']=['xxx','yyy',....]

What should I do here. Your any help will greatly appreciated.

I assumed that you are struggling with nested ng-repeat. Hope the following code will help you.

HTML

<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>

<div ng-app="myApp" ng-controller="myCtrl">

	<div ng-repeat="item in artType">    
	<select ng-model="ddlArtType">
		<option value="" disabled selected> </option>
		<option ng-repeat="selectedArtType in artCultureDependencyMap[item] track by $index">
			{{selectedArtType}}
		</option>
	</select>    
</div>

</div>

<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
	
	$scope.artType=['Film', 'Music', 'Sports'];
	
	$scope.artCultureDependencyMap = {};
	$scope.artCultureDependencyMap['Film'] = ['Film1', 'Film2', 'Film3'];
	$scope.artCultureDependencyMap['Music'] = ['Music1', 'Music2', 'Music3'];
	$scope.artCultureDependencyMap['Sports'] = ['Sports1', 'Sports2', 'Sports3'];
});
</script>

</body>
