Customise the form with repeatable fields

Hi,

nice plugin i like it,

i have a question:is it possible to let users in frontend after filling the fields(one block of fields in one row) to add a button plus(+) and when the user click on this button add a new line of the same block of fields appears??(for exemple add some code javascript when the user click on the button add).

Thanxs
