#original_collection_select ⇒ Object

Override default Rails collection_select helper to handle lambdas/procs in text and value methods, so it works the same way as collection_radio_buttons and collection_check_boxes in SimpleFormWithClientValidation. If none of text/value methods is a callable object, then it just delegates back to original collection select.
