Wayfinder menu -apply styles only to the first button

Hello,
in the wayfinder chunk "row" is the code:
<li><a href="[+wf.link+]"><img src="assets/template/images/m_[+wf.docid+]_off.gif" class="roll" border="0"></a>[+wf.wrapper+]</li>

I need to apply an additional style in the class tag when the wf.docid has the value 4.

How can do this?

Thanks for helping

I’m guessing this question is very much in the wrong section, but alas.

WayFinder has options for seperate styling of the First and the Last of every group (main, and children)

I`m sorry, I should read the entire wiki doc. Anyway, thank you for your advice

One thing to remember is that once you set up a row tpl it will be used for all rows AND sub rows, to have different sub rows you need to add a innerRowTpl as well
