Dynamically creation of text boxes through a buttonClick

Hello,
I am working on form for CV automation. I stuck with work experience.
Workflow is the next: Some candidate may have no WE (work experience) and the others may have different "amount" of WE.
So I need to have dynamic button, which will create another set of fields (4 fields) for another WE, and to drag button below new WE textboxes.

Please find the attachment below. On user form I ve manually added another WE2 set of fields. Just to explain you better.

Thanks in advance!
