Sample text

To add an override for visual elements to my polyfill, I can leverage the built-in op tions object required by all Kendo UI widgets. In Example 3-3, we used this object to specify the name of our widget, Form, which Kendo UI uses when adding our polyfill to the library namespace. I can use this object to specify any number of developerdefined features, and I’ll use it now to add an alwaysUseWidgets Boolean value. Once I’ve added that option, I’ll modify my isFormTypeSupported method to check for this property.
