Kentico CMS allows you to modify some of the system tables and enhance them with custom attributes. You can edit them in Site Manager -> Development -> System tables.


If you add a new column to a system table, it is available on the Custom fields tab of the corresponding dialog. For example, if you add a custom column to the CMS_User table, it will be displayed in Site Manager -> Administration -> Users -> Edit (Edit) user on the Custom fields tab.






When creating a new field in a system table, the Allow empty value property is set to TRUE and cannot be edited. This is necessary to ensure that the default system procedures continue to work correctly.


However, you can change this value to FALSE to make the field required in alternative forms.
