menu wordpress – attribuer une classe spécifique de liste à l’ancre

// managing divider: add divider class to an element to get a divider before it.
$divider_class_position = array_search('divider', $classes);
if($divider_class_position !== false){
    $output .= "<li class="divider"></li>n";
    unset($classes[$divider_class_position]);
}

Solution n°1 trouvée

Sur $attributes, affichez simplement Link active et survolez l’effet, aucune classe spécifique n’est définie dans link .

Solution n°2 trouvée

Vous devez rechercher :

$item_output .= '<a'. $attributes .'>';

et remplacez-le par :

$item_output .= '<a'. $attributes .' class="'.$classes[0].'">';

Maintenant, il change <li class="icon-home list-item">pour<a href="index.php" class="icon-home">
