"appendTo / after" each item with $(this)?

"appendTo / after" each item with $(this)?

Hi!

I'm trying to move a div inside a container for each instance of that class.
But when using the script below, it moves every single matching div below all the matching "group fields".

My jQuery now:
$('.field-1').insertAfter('.group .field-2');

The code:
<div class="container container-1">
  <div class="field-1"></div>
  <div class="group">
    <div class="field-2"></div>
  </div>
</div>

<div class="container container-2">
  <div class="field-1"></div>
  <div class="group">
    <div class="field-2"></div>
  </div>
</div>

I want to move the div "field-1" after/below "field-2" for each repeating container.

A little help? I'm guessing that I need a small function that uses $(each) or $(this)?

Regards,
Mattias
