Specifies whether the widget changes its state when a user pauses on it.

Type:

Boolean

Default Value: false

items

An array of items displayed by the widget.

Type:

Array<String | Object>

Raised Events: onOptionChanged

Generally, the array of items is auto-generated when a validation result is ready. And if you set a custom array of items, it will be overridden by the auto-generated array. So use this option to read the current array of items. Alternatively, you can set the array of items generated by a custom validation engine.

Specifies the validation group for which summary should be generated.

In the Knockout approach, the ValidationSummary widget should be added to the div element representing the ValidationGroup component. In this instance, you do not have to specify the validationGroup option for the ValidationSummary widget.

If you use the JQuery approach, the validationGroup option should be specified for the ValidationSummary widget to generate a summary for a particular validation group. Assign the validation group name that is specified for the validationGroup option of the validators that extend the editors to be validated.
