#### Configuration
{width="600"}
In addition to the parameters that are [common](/manual/web_interface/frontend_sections/dashboards/widgets#common-parameters) for all widgets, you may set the following specific options:
| | |
|--|--------|
|*Host groups*|Select host groups to display in the widget.
Alternatively, select a compatible widget as the [data source](/manual/web_interface/frontend_sections/dashboards/widgets/#dynamic-parameters) for host groups.
This field is auto-complete, so starting to type the name of a group will offer a dropdown of matching groups.
Specifying a parent host group implicitly selects all nested host groups.
Host data from these host groups will be displayed in the widget; if no host groups are entered, all host groups will be displayed.
This parameter is not available when configuring the widget on a [template dashboard](/manual/config/templates/template#adding-dashboards).|
|*Exclude host groups*|Select host groups to hide from the widget.
This field is auto-complete, so starting to type the name of a group will offer a dropdown of matching groups.
Specifying a parent host group implicitly selects all nested host groups.
Host data from these host groups will not be displayed in the widget. For example, hosts 001, 002, 003 may be in Group A and hosts 002, 003 in Group B as well. If we select to *show* Group A and *exclude* Group B at the same time, only data from host 001 will be displayed in the dashboard.
This parameter is not available when configuring the widget on a [template dashboard](/manual/config/templates/template#adding-dashboards).|
|*Hosts*|Select hosts to display in the widget.
Alternatively, select a compatible widget or the dashboard as the [data source](/manual/web_interface/frontend_sections/dashboards/widgets/#dynamic-parameters) for hosts.
This field is auto-complete, so starting to type the name of a host will offer a dropdown of matching hosts.
If no hosts are entered, all hosts will be displayed.
This parameter is not available when configuring the widget on a [template dashboard](/manual/config/templates/template#adding-dashboards).|
|*Scenario tags*|Specify tags to limit the number of web scenarios displayed in the widget.
It is possible to include as well as exclude specific tags and tag values. Several conditions can be set. Tag name matching is always case-sensitive.
There are several operators available for each condition:
**Exists** - include the specified tag names;
**Equals** - include the specified tag names and values (case-sensitive);
**Contains** - include the specified tag names where the tag values contain the entered string (substring match, case-insensitive);
**Does not exist** - exclude the specified tag names;
**Does not equal** - exclude the specified tag names and values (case-sensitive);
**Does not contain** - exclude the specified tag names where the tag values contain the entered string (substring match, case-insensitive).
There are two calculation types for conditions:
**And/Or** - all conditions must be met, conditions having the same tag name will be grouped by the *Or* condition;
**Or** - enough if one condition is met.|
|*Show hosts in maintenance*|Include hosts that are in maintenance in the statistics.
This parameter is labeled *Show data in maintenance* when configuring the widget on a [template dashboard](/manual/config/templates/template#adding-dashboards).|
