Menu Position is a great Drupal Module to get the .active-trail class in the menu, without adding eg. all news article nodes to the it.
The only problem is a „placeholder“ link created instead, class: „.menu-position-link“. It seems this is technically necessary.
Here is a little jQuery function to remove the element itself, the container menu (if its the only item) and fix the causing classes. You may have to alter it a bit.
Remove the console.logs before using it on productive environment!
$('.menu', context).children('li.active-trail').each(function() {
var menuChildCount = $(this).children('.menu').children('li').length;
var $menuPosLinkParent = $(this).find('.menu-position-link').parent();
if ($menuPosLinkParent.length) {
console.log('Found one - childcount:' + menuChildCount);
console.log($menuPosLinkParent);
if (($menuPosLinkParent).hasClass('last')) {
console.log('Its the last item.');
// If its the last link move class .last to the menu item before
$menuPosLinkParent.prev('li').addClass('last');
}
if (menuChildCount === 1) {
console.log('Its the only item.');
// If menu position link is the only menu-item, remove parent trails .expanded
$menuPosLinkParent.parents('li.active-trail.expanded').removeClass('expanded');
$menuPosLinkParent.parent('.menu').remove();
console.log('Removed it.');
} else {
$menuPosLinkParent.remove();
console.log('Removed it.');
}
}
});
