I have a generic list
<div id="banner">
<div class="oneByOne_item top_offers">
<div class="top_offer_wrap">item1</div>
<div class="top_offer_wrap">item2</div>
<div class="top_offer_wrap">item3</div>
<div class="top_offer_wrap">item4</div>
<div class="top_offer_wrap">item5</div>
<div class="top_offer_wrap">item6</div>
</div>
</div>
But what I want to do is
<div id="banner">
<div class="oneByOne_item top_offers">
<div class="top_offer_wrap">item1</div>
<div class="top_offer_wrap">item2</div>
<div class="top_offer_wrap">item3</div>
</div>
<div class="oneByOne_item top_offers">
<div class="top_offer_wrap">item4</div>
<div class="top_offer_wrap">item5</div>
<div class="top_offer_wrap">item6</div>
</div>
</div>
I could use any advice as to the best way to deal with this situation.
