#original_options_from_collection_for_select ⇒ Object

Override Rails options_from_collection_for_select to handle lambdas/procs in text and value methods, so it works the same way as collection_radio_buttons and collection_check_boxes in SimpleForm. If none of text/value methods is a callable object, then it just delegates back to original collection select. FIXME: remove when support only Rails 4.0 forward
