How to display an Enum as a <select> in Advanced Search filters?

[Marco Cirillo]

I have an enum on an entity, Review.Type, that I would like to have show up as a <select> in the Advanced Search section, but I'm unsure how to accomplish this:

@Override
public FiltersConfigurationUnit filters(final FiltersConfigurationUnitBuilder filterBuilder ) {
    return filterBuilder
            .filter("Business", "business")
            .filter("User", "user")
            .filter("Type", "type")
            // This doesn't work, but I want `type` to have a <select> with 'good' and 'bad' as options
            .renderer(enumeration( 
                    EnumElement.element(Review.Type.GOOD.toString(), "Good"),
                    EnumElement.element(Review.Type.BAD.toString(), "Bad")
            ))
            .filter("Is Premium?", "isPremium")
            .filter("Is Confirmed?", "isConfirmed")
            .build();
}
