[Category] How Can I Add A Level Class For Each Level

[pierrot10]

Good morning,

I have have some dificultie to set my css of my category tree.

It would be simpler if I could add a level class for each level as this exemple

 

<ul>


<li class="level1">level1</li>
<li class="level1">
<ul>
<li class="level2"></li>
<li class="level2">
<ul>
<li class="level3"></li>
</ul>
</li>
</ul>
</li>
</ul>

 

Do you see?

Thank
