System tables

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.

 

When you add a new column to the user profile, it's available on the Custom fields tab of the User properties dialog.

 

 

 

Always allow empty values

 

When creating a new empty field in a system table, it's highly recommended that you always allow empty values in the newly created field, so that the system procedures and existing dialogs keep working.
