Trying to add a new field from user end.

Hi,
I am using a community builder to create registration. As I need some functionality from where user can add multiple data using text box. As an example a user adding his qualification when he fills up the data and click add button another text box will appear. Can I do that functionality using community builder or any of its add on?

Users can't add fields. You'd need to create multiple fields for your users in CB > User Management then you could create a dropdown to select how many they want then use CB Conditional to display the amount they selected by show/hiding them based off the dropdown fields value.
