Yeah, so in content type fields like Article or any other when you add a field it has an option 'Number of values' and if you select Unlimited it adds a button 'Add another item' when creating a content.
So I was thinking is it possible to do that with Webform module's forms? Let's say a user is filling in the form, let's say he fills in his phone number into Phone number field and then maybe he has a another phone number, so he could click 'Add another item' and that would open up a second field of a Phone Number field.
To be exact, I need that Unlimited option to work on Webform fieldset fields. So if I have a fieldset of three fields, I can click 'add another item' and it opens up a 2nd fieldset.
