Increase input lines while filling a form

[MamadouPathe_DIALLO]

Hello all,

I am trying to implement a use case in a form in JSM in which there is an input field (lines), that can be increased as needed. 

Eg: something similar to the table below

                        Header1| header2| header3

line 1

line 2

(add new line)

Is there a way to do this in a form?

Best regards
