Hello, I''ve been using the brilliant awesome_nested_set gem to manage pages and their parents on my app, however I''ve run into what appears to be a simple challenge... I use the helper nested_set_options to make life easier - however I can''t see if there is an easy way I can get it to return a NULL option at the top of the select list? This would allow me to create pages that are roots. Any advice would be greatly appreciated. Kind regards, Ian
