@karsontse1337 .....if you're using repeating section then controls within repeating section cannot be connected to SharePoint list columns. But yes, you can add choice control and provide choices from the control. If you have multiple controls in the repeating section and you want that information to manipulate or to use to create new items in a new list then you can add that repeating section in a panel and then connect that panel to a multi-line text box in SharePoint (but make sure it's plain text). When you create rows in repeating section, you'll see XML code in this multi-line text column which you can manipulate using Nintex workflow's "Query XML" and "Update XML" actions. You can also even insert more rows to your repeating section using update XML action.
