rhodesignHi all
I need some help modifing the Navigation Plugin "Navigo" from http://www.adahas.com/work/navigo/.
Usualy Navigo creates nested Lists for Submenu-Pages Like:
<ul id="level1">
<li id="level1active"><a id="level1current" href="" title="Link1">Link1</a>
<ul id="level2">
<li><a href="" title="Level2 Link">Level2 Link</a></li>
</ul>
</li>
</ul>Because I want to create the Level1 Navigation with Cufon Font Replacement, I should have Level2 outside of the active li, like...
<ul id="level1">
<li id="level1active"><a id="level1current" href="" title="Link1">Link1</a></li>
<ul id="level2">
<li><a href="" title="Level2 Link">Level2 Link</a></li>
</ul>
</ul>Would be very grateful if someone can help me out with this issue because my PHP-Skills aren`t that good.
Here is the navigo.php File that creates the nested Lists.
