Recursing nested array in blade template

I am attempting to loop out a menu in Laravel.

I am passing the nested array to the main blade template categories-management.blade.php.

View::make('categories-management')->with('categories', $categories);

Where $categories is

array (size=3)
  'Business Resources' => 
    array (size=7)
      'Operations' => 
        array (size=4)
          'resource_type_id' => int 1
          27 => 
            array (size=3)
              'id' => int 27
              'name' => string 'Design & Development' (length=20)
              'children' => 
                array (size=2)
               ... truncated ...

I am then kicking of the menu inside of categories-management.blade.php with this:

@include('/includes/category-menu-item', array('categories', $categories))

Inside includes/category-menu-item I have the following loop:

@if(is_array($categories))
<ul>
    @foreach($categories as $key => $value)
    <li>
        @if(!is_numeric($key)) 
            <p>{{$key}}</p>
            @include('/admin/includes/category-menu-item', array('categories', $value))
        @else
            <button data-category-id="{{$value->id}}">{{$value->name}}</button>
            @include('/admin/includes/category-menu-item', array('categories', $value->children))
        @endif
    </li>
    @endforeach
</ul>
@endif

This is still obviously incomplete but I already have issues where the template never gets past the first layer and prints out:

How do I get Laravel to recognise the new array value? Or is there a better method for this?

Your @include statements are not correct. The data passed to view need to be an associated array, you have passed an array with numeric keys. You have to change from array('categories', $value) into array('categories' => $value):

@if(is_array($categories))
<ul>
    @foreach($categories as $key => $value)
    <li>
        @if(!is_numeric($key)) 
            <p>{{$key}}</p>
            @include('/admin/includes/category-menu-item', array('categories' => $value))
        @else
            <button data-category-id="{{$value->id}}">{{$value->name}}</button>
            @include('/admin/includes/category-menu-item', array('categories' => $value->children))
        @endif
    </li>
    @endforeach
</ul>
@endif
