### Description

These parameters and the possible property values for the respective dashboard widget field objects allow to configure
the [*System Information*](/manual/web_interface/frontend_sections/dashboards/widgets/system) widget in `dashboard.create` and `dashboard.update` methods.

::: noteimportant
Widget `fields` properties are not validated during the creation or update of a dashboard.
This allows users to modify [built-in widgets](/manual/web_interface/frontend_sections/dashboards/widgets) and create [custom widgets](/devel/modules/tutorials/widget), but also introduces the risk of creating or updating widgets incorrectly.
To ensure the successful creation or update of the *System information* widget, please refer to the parameter behavior outlined in the tables below.
