CustomTemplate | API Reference | ArcGIS Maps SDK for JavaScript 4.31

Defines the custom layout template options used by the Print widget to generate the print page. While custom templates can be published from ArcGIS Pro to a portal, custom layout templates are defined in a portal, where they can be added, removed, or edited as necessary without having to republish the print service. There are a limited number of options available for customization.

The main benefit of this class is that it allows developers to give a name to a preferred format and layout and if there should be a Legend present or not, in a reusable way. This is what the UI looks like in a portal:
