Hallo zusammen
Ich arbeite mit Wordpress und nutze da für die Navigation ein Plugin namens "Navigo". Diese Plugin ist ideal um aufklappbare Navigationen zu erstellen.
Nun habe ich folgendes Problem:
Da ich die Level1 Navigation in einer speziellen Schrift haben muss, was ich mit Cufon realisiere, darf die zweite Navigationsebene nicht im aktiven Listenpunkt verschatelt sein.
Normalerweise generiert das Script folgender Code:
HTML-Code:
<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>
Ich müsste aber eben die ul#level2 ausserhalb des aktiven li`s haben, so in der Art:
HTML-Code:
<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>
Wer könnte mir helfen das PHP-Script so anzupassen damit Subnavipunkte ausserhalb des aktiven Listenpunktes kommen?
Wäre wirklich sehr dankbar!
Hier noch das PHP-Script das die verschatelte Liste erstellt:
PHP-Code:
