You would have to set form_ui = :hidden on after_render_field (controller
method). If you
do that you should set form_ui on do_edit and do_new also (or before_filter
:set_column_form_ui, :only => [:new, :create, :edit, :update])
Also you can override field_attributes(column, record) helper to set a class
(it will be used
on dl tag) then you can hide with css.
def field_attributes(column, record)
if conditions_to_hide_column
{:class => '...'}
else
super
end
end
