Enabling full user customization of forms is the highest level that can be set for user personalization of forms. This level requires that you set the AllowUserSetup property on the form control and set the AllowAdd property on the form data source field to Yes.

Users can customize the layout and add new fields from the Setup form (available in the shortcut menu for open forms).

To support this level of personalization, you must move all code to the data source fields. If a control is added to a form by a user, no code is attached and the properties are the default values for that type of control and data.

By default, only fields that are already present in the form can be added; however, this can be changed at design-time.

Note
Only data fields can be added. The user cannot add unbound controls or controls bound to display methods.
