Overriding Core Widget Properties

You can override the default values of existing core widget properties in exactly the same way as you create properties of your own - by adding a properties/feature resource to the widget that contains definitions of the properties you want to override. To set the default value of the Teaser widget's field.markup.tag.subtitle property to h4, for example, you would need to add a teaser/properties/feature resource containing the following property definition:

wf.props.teaser.field.markup.tag.subtitle = h4
