| Display name | Name of the new cloned web part used in the administration interface. | 
| Code name | Name of the new cloned web part used in website code. | 
| Category | Select category where the new cloned web part will be placed. | 
| File name | Parent web part which will be used as a source for the newly cloned web part. Enter the path to the file under ~/CMSWebParts folder. E.g. AbuseReport/AbuseReport.ascx. |
