| 11 `paper-radio-group` allows user to select only one radio button from a set. | |
| 12 Checking one radio button that belongs to a radio group unchecks any | |
| 13 previously checked radio button within the same group. Use | |
| 14 `selected` to get or set the selected radio button. | |
| 15 | |
| 16 Example: | |
| 17 | |
| 18 <paper-radio-group selected="small"> | |
| 19 <paper-radio-button name="small" label="Small"></paper-radio-button> | |
| 20 <paper-radio-button name="medium" label="Medium"></paper-radio-button> | |
| 21 <paper-radio-button name="large" label="Large"></paper-radio-button> | |
| 22 </paper-radio-group> | |
