</ul>
</ul>
</div>
&outerTpl=`yourOuterTemplate`
<ul id="yourID"> [[+wf.wrapper]] </ul>
But your Wayfinder call is missing a backtick ``, try this and called it uncached while developing:
[[!Wayfinder? &startId=`7` &level=`1` &rowTpl=`TabbedContentRowTpl`]]
Also check your rowTpl chunk. It’s outputting a whole lot of additional <ul> tags. From your page source:
<div id="tabs"> <ul> <ul><ul><li class="first"><a href="index.php?id=8" title="Description">Description</a></li></ul> <ul><li><a href="index.php?id=16" title="Hotels">Hotels</a></li></ul> <ul><li class="last"><a href="index.php?id=17" title="Culture">Culture</a></li></ul> </ul> </ul> </div>
<script type="text/javascript">
$(function() { $("#tabs").tabs(); });
</script>
<div id="tabs">
[[!Wayfinder? &startId=`7` &level=`1` &outerTpl=`TabbedContentOuterTpl` &rowTpl=`TabbedContentRowTpl`]]
</div><ul id="yourID"> [[+wf.wrapper]] </ul>
This was actually resolved by removing the <ul> tags surrounding the Wayfinder call as suggested by jepedia.
The &outerTpl is useful but doesn’t seem necessary, though probably come in handy for formatting.
Here is my new working code for the Resource Content:
<script type="text/javascript"> $(function() { $("#tabs").tabs(); }); </script> <div id="tabs"> [[!Wayfinder? &startId=`7` &level=`1` &outerTpl=`TabbedContentOuterTpl` &rowTpl=`TabbedContentRowTpl`]] </div>
and the &outerTpl is a direct copy of jepedias for now:
<ul id="yourID"> [[+wf.wrapper]] </ul>
