"+" for a group of custom fields

Hi there,

Version: 1.3.28 with active subscription ;-)

We are currently trying to push forward on a community portal for musicians in germany. We are facing an issue at the moment with creating a group of custom fields for the standard user profile.

we need the possibility to create a group of custom fields (i.e. for a musical instrument) and give a frontend user the possibility to multiply this group of fields by clicking on a "+" symbol.

backend would be like this:


is it in any way possible for a frontend user to get the "+" for adding another intrument (ie adding the whole group of custom fields) again?

Thanks in advance


Marco
