angularjs dynamic-data forms javascript json

AngularJS dynamic form from json data (different types)

I try to create a dynamic form in AngularJS using the data from a JSON. I have this working:

HTML

    <p ng-repeat="field in formFields">
<input
dynamic-name="field.name"
type="{{ field.type }}"
placeholder="{{ field.name }}"
ng-model="field.value"
required
>
<span ng-show="myForm.{{field.name}}.$dirty && myForm.{{field.name}}.$error.required">Required!</span>
<span ng-show="myForm.{{field.name}}.$dirty && myForm.{{field.name}}.$error.email">Not email!</span>
</p>
<button ng-disabled="myForm.$invalid">Submit</button>
</form>

JS

angular.module('angularTestingApp').controller('DynamicFormCtrl', function ($scope) {
$scope.formFields = [
{
name: 'firstName',
type: 'text'
},
{
name: 'email',
type: 'email'
},
{
name: 'password',
type: 'password'
},
{
name: 'secondName',
type: 'text'
}
];}).directive("dynamicName",function($compile){
return {
restrict:"A",
terminal:true,
priority:1000,
link:function(scope,element,attrs){
element.attr('name', scope.$eval(attrs.dynamicName));
element.removeAttr("dynamic-name");
$compile(element)(scope);
}
}});

This code works, but the question is that I dont know how to add dynamic checkbox or checklist and how can I validate inside the form, something like this:

angular.module('angularTestingApp')

.controller(‘DynamicFormCtrl’, function ($scope) {

$scope.formFields = [
{
name: 'firstName',
type: 'text'
},
{
name: 'email',
type: 'email'
},
{
name: 'password',
type: 'password'
},
{
name: 'city',
type: 'checkbox',
choices: [
{ name: "red" },
{ name: "blue" },
{ name: "green" },
]
}
];})

Thank you in advance for your attention.
Best Regards!

I have solved my problem.
