Hi,
I’ve been able to do it.
For those who need to do the same. Here is the answer.
I finally used this code specifying the id of the wished category
<?php wp_list_cats(‘sort_column=id&optioncount=0&use_desc_for_title=0&list=1&child_of=2637’); ?>
I then added a specific
<ul class=”nameityourself”><?php wp_list_cats(‘sort_column=id&optioncount=0&use_desc_for_title=0&list=1&child_of=2637’); ?>
That’s all. Use the CSS to display it like you want
