title: Nested new $loop function Laravel PHP
body: <p>I wanted to assign a property to the first element of each serie (Value1) and y tried to do with the new Laravel $loop variable but nesting doesn't work. I tried to use $loop->first, but only works one on the first Group.</p>
  
  <p>I tried to do the next:</p>
  
  <pre><code>- Group 1     $loop-&gt;index = 0 (parent)
    - Value 1   $loop-&gt;index = 0
    - Value 2   $loop-&gt;index = 1
    - Value 3   $loop-&gt;index = 2
  
  - Group 2     $loop-&gt;index = 1 (parent)
    - Value 1   $loop-&gt;index = 3
    - Value 2   $loop-&gt;index = 4
  </code></pre>
  
  <p>Seems the $loop->index (child) doesn't start a new serie.
  What can I do?</p>
