Provide a way to return JSON object of entire form layout along with fields and field options.

[mofman]

Currently we have to pull out form layout and fields using the follow script, but it would be helpful if there was a method to return layout and field settings out of the box.

{% macro defaultOption(field) %}
    {% set output = "''" %}
    {% if field.type in ["radio_group", "select"] %}
        {% for option in field.options %}
            {% if option.checked %}
                {% set output = "'" ~ option.value ~ "'" %}
            {% endif %}
        {% endfor %}
    {% elseif field.type in ["multiple_select", "checkbox_group"] %}
        {% set output = '[]' %}
        {# {% for option in field.options if option.checked %}
            {% set output = '[' ~ option.value ~ ']' %}
        {% endfor %} #}
    {% endif %}
    {{ output }}
{% endmacro %}
