Ok here is what I got:
outerTpl:
<div id="nav">
[+wf.wrapper+]
</div>
rowTpl:
<ul class="select">
<li>
<a href="[+wf.link+]">[+wf.linktext+]<!--[if IE 7]><!--></a><!--<![endif]--><!--[if lte IE 6]><table><tr><td><![endif]-->
[+wf.wrapper+]
</li>
</ul>
innerTpl:
<ul class="sub">
[+wf.wrapper+]
</ul><!--[if lte IE 6]></td></tr></table></a><![endif]-->
innerRowTpl:
<li><a href="[+wf.link+]">[+wf.linktext+]</a></li>
The call:
[[Wayfinder? &startId=`0` &level=`2` &outerTpl=`outerTpl` &innerTpl=`innerTpl` &rowTpl=`rowTpl` &innerRowTpl=`innerRowTpl` &cssTpl=`cssplay_css` ]]
The css chunk:
<style type="text/css">

</style>
Up to here it is working, this will give the basic dropline menu.
I was able to get the current parent to work as well with the activeParentRowTpl but here it started to breakdown:
<ul class="current">
<li><a href="[+wf.link+]">[+wf.linktext+]</a></li>
</ul>
[+wf.wrapper+]
But at this point the current sub will not work. The catch is that the menu uses two structures, in the normal state the subs are nested <ul> but in the active state they are independent <ul> so you would need a innerActiveParent or something like that ( I may have overlooked something or not be thinking outside or inside the box). There may be a way to use a combination of tpl and classes to get this to work but I am stumped at this point. Hope someone can follow up from this point
