Here is an example of how to do multi-lingual navigation using the navtool. You need to have your language keys set up and then make each page title a language key and then the following should work.
#set($list = $navtool.getNav("/")) #foreach($n in $list) <li class="divider"></li> #set($children = $n.children) #if($children && $children.size() > 0) <li class="has-dropdown #if($n.active) active #end"> <a href="${n.href}">$text.get( ${n.title} )</a> <ul class="dropdown"> #foreach($ch in $children) <li #if($ch.active) class="active" #end><a href='${ch.href}'>$text.get( ${ch.title} )</a></li> #end </ul> </li> #else <li class="#if($n.active) active #end"><a href='${n.href}'>$text.get( ${n.title} )</a></li> #end #end
