How to add multiple input box dynamically with dropdown in angularjs - angularjs

Question

I am having this problem which I can't find the solution to.
1) I have a dropdown list which the data is pull in from a json file
2) When the user selects a item I want to dynamically add a input box without a button.
Got a jQuery code but wanted to do it the angular way, but read that ng-Change is not the same as jquery .change?
Can anyone help or point me into the right direction of how to do this.
HTML
<div class="main-content__right" ng-controller="QuestionController">
<div ng-repeat="element in questionList">
<fieldset>
<div id="add-more" class="well">
<div class="field">
<div style="width:100%;" class="dropdown">
<select name="{{options.name}}" id="select" data-ng-model="formData"
data-ng-options="options as options.label for options in element.inputElement | orderBy:'label'"
ng-change="onCategoryChange(formData)">
<option value="" data-id="null" disabled="" selected="">Select an item...</option>
</select>
</div>
</div>
{{formData}}
</div>
</fieldset>
</div>
app.js
var app = angular.module("cab", []);
app.controller('QuestionController', function($scope) {
var $scope.formData = {};
$scope.questionList = [{
"sectionTitle": "Travel",
"subTitle": "How much do you spend on these items for your car?",
"inputType": "select",
"inputElement": [{
"label": "Public transport",
"name": "travelOutgoing",
"helpInfo": "include train journeys",
"type": "select"
}, {
"label": "Taxis",
"name": "travelOutgoing",
"type": "select"
}, {
"label": "Bicycle",
"name": "travelOutgoing",
"helpInfo": "general running costs such as repair or rental",
"type": "select"
}, {
"label": "Car rental",
"name": "travelOutgoing",
"helpInfo": "include fuel, parking charges and tolls",
"type": "select"
}
]
}];
$scope.onCategoryChange = function () {};
});

Answer 1

Your controller function needs to add each selection to an array on scope:
Controller
app.controller('QuestionController', function($scope) {
$scope.formData = [];
$scope.selectedValue = {};
$scope.questionList = [{
"sectionTitle": "Travel",
"subTitle": "How much do you spend on these items for your car?",
"inputType": "select",
"inputElement": [{
"label": "Public transport",
"name": "travelOutgoing",
"helpInfo": "include train journeys",
"type": "select"
}, {
"label": "Taxis",
"name": "travelOutgoing",
"type": "select"
}, {
"label": "Bicycle",
"name": "travelOutgoing",
"helpInfo": "general running costs such as repair or rental",
"type": "select"
}, {
"label": "Car rental",
"name": "travelOutgoing",
"helpInfo": "include fuel, parking charges and tolls",
"type": "select"
}]
}];
$scope.onCategoryChange = function(selectedItem) {
$scope.formData.push(selectedItem)
};
});
Then you can use an ng-repeat to render all of the items in formData.
HTML
<fieldset>
<div id="add-more" class="well">
<div class="field">
<div style="width:100%;" class="dropdown">
<select name="{{options.name}}" id="select" data-ng-model="selectedValue" data-ng-options="options as options.label for options in element.inputElement | orderBy:'label'" ng-change="onCategoryChange(selectedValue)">
<option value="" data-id="null" disabled="" selected="">Select an item...</option>
</select>
</div>
</div>
<div ng-repeat="item in formData track by $index">
<input ng-model="item.label" />
</div>
</div>
</fieldset>
