Widget
A widget is a superset of an Angular directive that is tightly coupled to a server-side JavaScript code block powered by the Rhino engine under the ServiceNow platform.
Since widgets are read-only
to benefit from future updates, you can't update their code. If you need to make major changes,
clone the widget and give it another name
and id
.
Widget Instance
Once you drop a widget into a column using the Service Portal Designer it will create a widget instance. A widget instace is a reference to a widget that contains: location, properties and CSS especific for that instance. A widget used multiple times in the same page, will use multiple instances.
