Listing directories on laravel?

Question

Cataloging

Good afternoon to all readers, please tell me why this construction does not work:

@forelse ($gro as $gr)
       <div class="container"> 
    <div class="col-md-5">
        <h1><p><strong>{{$gr->name_group}}</strong></p></h1>
    </div></div>
       
      <?php $fi=$find->where('c_id_group_item', $gr->c_id_group); ?> 

       @if($fi)
  @include('items', ['items' => $fi])
@endif

@empty
БЛА БЛА БЛА!
    @endforelse

When the execution occurs in the items template, the structure turns out to be correct, but for some reason the items themselves display one for the group, please tell the knowledgeable people what I'm doing wrong, or how best to implement it, thanks ...
Yes, the items template code:

@foreach ($items as $fi)
   <div class="container"> 
    <div class="col-md-5">
 @if (!empty(($fi->number)&& ($fi->shortname)))  
    {{$fi->name_item}}
  </div>
</div>
 @endif
@endforeach

$fi is filled with sorting....

Answer 1

<?php $fi=$find->where('c_id_group_item', $gr->c_id_group); ?>

What is it? Why not use normal relationships in the model (hasMany for example)
