Add a span and class to menu items that has children
Menu items with no children has the class="leaf". It is possible to style the menu items li (has children) and then cancel the rule-set for the class li.leaf (has no children).

A span can be added to all li's (set to display:none for leafs).
How do I insert a &lt;span&gt; &lt;/span&gt; tag inside the &lt;a&gt; &lt;/a&gt; tag on my main menu
