nav -> instead of active "a" tag I want to use "span"

[Zeromax]

Just on the way to get bootstrap working with contao. And there I have a Problem, wich I do not want to solve with changing the template (Thats possible, I tried)

The Navbar is build like this

<ul class="level_1 nav">
        <li class="active submenu first dropdown"><span data-toggle="dropdown" class="active submenu first dropdown dropdown-toggle" title="Übersicht" href="uebersicht.html">Übersicht</span>
<ul class="level_2 dropdown-menu">
    <li class="first last"><a class="first last " title="Projekt Übersicht" href="projekt-uebersicht.html">Projekt Übersicht</a></li>
</ul>
</li>
    <li class="sibling"><a class="sibling " title="Projekte" href="projekte.html">Projekte</a></li>
    <li class="sibling"><a class="sibling " title="Aufgaben" href="aufgaben.html">Aufgaben</a></li>
    <li class="sibling"><a class="sibling " title="Diskusion" href="diskusion.html">Diskusion</a></li>
    <li class="sibling last"><a class="sibling last " title="FAQ" href="faq.html">FAQ</a></li>
</ul>

instead of havin an "a" Tag in the active Button there is a span. Is it Possible to add this span to the CSS Framework?

We won't be adding spans at this time.
