you can use recipe here http://doc.silverstripe.org/recipes:page_selection_for_special_menu

you just create checkbox in admin panel that will decide if the page will be shown in menu (you should create two)

static $db = array(
"ShowInTabMenu" => "Boolean"
);

function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab("Root.Behaviour", new CheckboxField("ShowInTabMenu", "Show special menu "));
return $fields;
}

then in page controller create functions, you shuold create two function e.g. headerMenu() nad footerMenu()

function topTabbers() {
$whereStatement = "ShowInTabMenu = 1 AND ShowInMenus = 1";
return DataObject::get("Page", $whereStatement);
}

then jus use $headerMenu or $footerMenu Page.ss

hi

I've created a module to deal with footer links, though I guess there is no reason why it could not be applied to header links also. Details can be found at http://weboftalent.asia/blog/links-module/
