| ----------------------- | ---------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- |
| Radio Option Selected   | When the parent group's custom state 'radio\_item\_' equals the option's 'item\_' custom state value | The radio icon changes to a filled dot icon with a dark background, indicating the option is selected |
| Expansion Input Visible | When Option 1 is selected (radio\_item\_ equals item\_ of Option 1)                                  | The hidden input field beneath Option 1 becomes visible and receives focus                            |
| Input Focused           | When the expansion input field is focused                                                            | A soft box shadow appears around the input field                                                      |
| Input Invalid           | When the expansion input field fails validation                                                      | Border turns red and a red box shadow appears around the input                                        |
| Input Disabled          | When the expansion input field is not clickable                                                      | Input opacity is reduced to 50%                                                                       |
