I need to show breadcrumb trail even when show in menu is unchecked. Can I override function and allow it to show somehow.
You can override the function by copying it from SiteTree.php and pasting it in your Page.php class. Then you can go nuts and edit it as much as you wish! I think the if show in menus check is a filter on a database query so you should be able to pick that out and delete it.
Thanks Willr.... simple and precise.
