I just can’t resolve this problem, i tried with this:
<ul class=”product-categories”><li class=”cat-item cat-item-17″>Bojleri

<li class=”cat-item cat-item-22″>SIME
<li class=”cat-item cat-item-23″>Vaillant

<li class=”cat-item cat-item-21″>Keramika
<li class=”cat-item cat-item-19″>Kotlovi
<li class=”cat-item cat-item-14″>Mje?alice za vodu
<li class=”cat-item cat-item-18″>Plamenici

but when i c/p this in html code it’s still the same.
