I am currently working on angular application , and client requirement is that he can add new controls (like radio button ,check box, textbox, dropdown or file uploader e.t.c) in the form with validations at runtime ,like google provide google forms as follow:

I tried to embed google forms in my application but I could not find any way by which user can create a new form using google forms in our native application, but I found the way by which we can embed the existing google form in our application(using iframe) and user can submit it, but I also need form creating at the same time.

I found the following script but it is execute in "Google App script":

var form = FormApp.create('New Form');
var item = form.addCheckboxItem();
item.setTitle('What condiments would you like on your hot dog?');
item.setChoices([
    item.createChoice('Ketchup'),
    item.createChoice('Mustard'),
    item.createChoice('Relish')
]);

If I do this task myself with Angular , then it is an itself a big project ,and client has not much time to implement this.

I just want to ask that is there any way(maybe I could not found but exists) by which we can embed google forms API in my application and user can create forms in my angular application, if yes then please give the idea or links.

If google not provide this option for developers ,then any other API (open source or paid) which provide such type of functionality.

Thanks
