Checkboxes and Radio Buttons?

Is there a way to have radio buttons populate after a checkbox is checked? For Example, users are given 5 checkboxes of choices of sports and once one or more is checked i would like radio buttons to populate so user can then select skill level for each sport they have checked. Is this possible?

Yes, you can do this.
Use conditional on radio buttons, and change the data source.
Try - when checkbox’s value is x
Data source - y.

This way you can change the data source for the radio buttons based on the value of checkbox.

Additionally, you can also keep the radio buttons hidden, and once a checkbox is selected, you show the radio buttons.
For this add the
Element is visible property along with the data source.
