Dynamically Set wrapper_attr for subfields of Repeatable fields?

[Mark West]

Hello, 

I would like to be able to dynamically set a class attributes for subfields of a Repeatable field I have defined in a role: App::Form::Role:Repeatable::People

Is that possible? In various documentation I've seen references to using build_update_subfields for similar attributes in Compound fields. 

In the field below, I would like to set width attributes narrower and wider depending on which fields are displayed on a form.

narrow

has_field 'household_people.person.first_name' => (

    label => 'First Name',

    label_attr => {'class' => 'label-medium'},

    do_wrapper => '1',

    wrapper_attr => {

        class=> ['col-xs-3', 'col-md-3'],

    },

    type => 'Text',

    required => '1',

    element_attr => {

        class => ['input-sm'],

    },

);

wider

has_field 'household_people.person.first_name' => (

    label => 'First Name',

    label_attr => {'class' => 'label-medium'},

    do_wrapper => '1',

    wrapper_attr => {

        class=> ['col-xs-6', 'col-md-6'],

    },

    type => 'Text',

    required => '1',

    element_attr => {

        class => ['input-sm'],

    },

);

Thanks,

Mark
