### Description
These parameters and the possible property values for the respective dashboard widget field objects allow to configure the [*Problems*](/manual/web_interface/frontend_sections/dashboards/widgets/problems) 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 *Problems* widget, please refer to the parameter behavior outlined in the tables below.

|*Host groups*|<|2|groupids.0|[Host group](/manual/api/reference/hostgroup/get) ID.
Note: To configure multiple host groups, create a dashboard widget field object for each host group with an incremented number in the property name.
This parameter is not supported if configuring the widget on a [template dashboard](/manual/api/reference/templatedashboard/object).|
|<|*Host groups (Widget)*|1|groupids.\_reference|Instead of [Host group](/manual/api/reference/hostgroup/get) ID:
`ABCDE._hostgroupids` - set a [compatible widget](/manual/web_interface/frontend_sections/dashboards/widgets#widget-compatibility) (with its *Reference* parameter set to "`ABCDE`") as the data source for host groups.
This parameter is not supported if configuring the widget on a [template dashboard](/manual/api/reference/templatedashboard/object).|
|*Exclude host groups*|<|2|exclude_groupids.0|[Host group](/manual/api/reference/hostgroup/get) ID.
Note: To exclude multiple host groups, create a dashboard widget field object for each host group with an incremented number in the property name.
This parameter is not supported if configuring the widget on a [template dashboard](/manual/api/reference/templatedashboard/object).|
|*Hosts*|<|3|hostids.0|[Host](/manual/api/reference/host/get) ID.
Note: To configure multiple hosts, create a dashboard widget field object for each host with an incremented number in the property name. For multiple hosts, the parameter *Host groups* must either be not configured at all or configured with at least one host group that the configured hosts belong to.
This parameter is not supported if configuring the widget on a [template dashboard](/manual/api/reference/templatedashboard/object).|

#### Configuring a *Problems* widget
Configure a *Problems* widget that displays problems for host group "4" that satisfy the following conditions:
- Problems that have a tag with the name "scope" that contains values "performance" or "availability", or "capacity".
- Problems that have the following severities: "Warning", "Average", "High", "Disaster".
In addition, configure the widget to show tags and operational data.
