Custom Attribute in the Component Meta Definition File
In the meta definition file for any standard component type, set the
type of the attribute for which you want to use a custom attribute editor to
custom and include an editor_definition element for the
attribute. The editor_definition includes the custom attribute editor ID and
optionally any configuration information that you want to pass to the custom attribute editor.
This example meta definition file for a banner includes three standard attributes: image of
type file, alt of type string, and size of type
enum. It also includes a custom attribute named Magic Unicorns, which is
assigned to the custom attribute editor with ID com.sfcc.magical. The options
for unicorns, for example, Auris and Chant, are listed in the configuration
element in the editor_definition and passed to the custom attribute editor.
