I have 2 dropdowns of which 1 dropdown is hidden which will be shown after selecting an option from the first select box
HTML CODE :
<div ng-repeat="choice in exSize">
<label>Attribute {{$index+1}} </label>

ANGULAR CODE :

$scope.sizeId = id;
angular.forEach($scope.modifyList,function(key,value){

}
For selecting one attribute and sub attributes it works fine. If I click on add attribute for second time the values int the first dropdown and sub dropdown gets null. Need some help in this part
I Took some liberty and made some implementation changes in your entire code by removing redundant code and scope objects and making the functionality more dynamic in nature.Here is a working plunker for the changes I've made.Still lot can be improved but I just answered your question at this moment.
Your changeSelect function will look like
$scope.changeSelect = function(id, index) {
$scope.sizeId = id;
angular.forEach($scope.modifyList, function(key, value) {
if (key.attributeid === id) {
$scope.hasArr[index] = key.attribuevaluelist;
}
})
};
Your HTML is changed to
<div ng-repeat="choice in exSize track by $index">
<label>Attribute {{$index+1}} </label>
<div id="select">
<select ng-model="choice.attributeid" ng-options="a.attributeid as a.attributename for a in modifyList" ng-change="changeSelect(choice.attributeid,$index)" class="minimal" required>
<option value="">Please Select An Attrtibute</option>
</select>
<label class="extra"><span class="plusCircle"><span id="addTaxBtn" ng-click="addSize($index)">+</span></span> Add Attribute<span ng-hide="exSize.length==1">/</span></label>
<label class="extra extra_remove" ng-hide="exSize.length==1"><span class="plusCircle"><span id="addTaxBtn" ng-click="rmSize($index)">-</span></span> Remove</label>
</div>
<!-- &&&& ng-if="choice.attributeid" &&&& -->
<!-- <div ng-repeat="(index1,sub) in subSize" ng-if="choice.attributeid"> -->
<div ng-repeat="sub in afterChangeAttr track by $index">
<div id="select" ng-show="choice.attributeid">
<div>
<div>
<select ng-model="sub.values[$parent.$index]" ng-options="v.attributevalue as v.attributevalue for v in hasArr[$parent.$index]" style="width:17%;margin-top:10px;">
<option value="">Select</option>
</select>
<input type="text" ng-model="sub.attributeprice" style="width:35%;" name="subAttr" ng-pattern="/^[0-9]+(\.[0-9]{1,2})?$/">
<label class="extra"><span class="plusCircle"><span id="addTaxBtn" ng-click="addSubSize(choice.attributeid)">+</span></span> Add<span ng-hide="afterChangeAttr.length==1 ||afterChangeAttr.length==5">/</span></label>
<label class="extra extra_remove" ng-hide="afterChangeAttr.length==1"><span class="plusCircle"><span id="addTaxBtn" ng-click="rmSubSize($index)">-</span></span> Remove</label>
</div>
</div>
<div ng-messages="addMenu.subAttr.$error" class="error" role="alert" ng-if="addMenu.subAttr.$dirty">
<div ng-message="pattern">Please Enter Only Numbers</div>
<div ng-message="required">Sales Price Is Mandatory</div>
</div>
</div>
</div>
</div>
I hope this resolves your issue.
