Add another / multiple - option

Hi,

I can't seem to find an answer to my problem but I'm sure it's been asked before so sorry for a possible double post.

Is there a way to create a webform component that an user can add multiple values with? Like this example. Would be perfect if this is possible with a fieldset and all it's containing components.

If this isn't possible with webform, is there any other (helper) module that can do this or some other way?

Thanx!
