I need some quick help on selecting items with jQuery. It might be a very simple solution, but... I can't see one right one besides cloning and duplicating elements.

So, here we go. I have this kind of structure on a page:

I want to group each six elements into a wrapper element, in order to have .quotesWrapper > (.sixQuoteWrapper > .quote * 6) * 4.

Any idea how i could achieve this? Thanks!

I'm sure i could get this without an each if i gave it a few more mins, but this works.

Here is a js fiddle

$('.quotesWrapper .quote.split').each(function(){
    $(this).nextUntil('.quote.split')
        .andSelf()
        .wrapAll('<div class="wrap" />')
});

@John Hartsock's solution is concise but inefficient because of the number of times the selectors are run. I would suggest a variation on his:

var i = 0, 
    quotes = $("div.quoteWrapper").children(),
    group;

while ((group = quotes.slice(i, i += 6)).length) {
    group.wrapAll('<div class="sixQuoteWrapper"></div>');
}

This solution runs a shorter selector just once and retrieves the children, making it faster.

I believe this is what you want. Essentially you loop through untill you have no more div.quote items under div.quoteWrapper. This is using the :lt() selector

while ($("div.quoteWrapper > div.quote").length) {
  $("div.quoteWrapper > div.quote:lt(6)").wrapAll('<div class="sixQuoteWrapper"></div>');
}
