I've worked with the wayfinder eBook from kongondo, which is aweseome, to create a splitted navigation with UltimateParent and Wayfinder.
Now I've the problem that the parent of the submenu-items is no marked as active. For example the document "awards" has three child documents, like "1" to "3". If "1" is selected, the active mark for "awards" vanishes. The parent of the splitted submenu is not marked active, when a submenu item is visited.
[[Wayfinder? &startId=`0` &outerTpl=`nav` &rowTpl=`nav-item` &hereTpl=`nav-item-active` &level = `1` &hereId= `[[UltimateParent]]` ]]
[[!Wayfinder? &startId=`[[UltimateParent]]` &outerTpl=`sidenav` &rowTpl=`sidenav-item` &hereTpl=`sidenav-item-active` &level = `1` ]]
It's difficult to find because attachments no longer work in the Forums.
