I need some guidance:

I want to generate Grouped dropdown for backend form.

I pass an array with nested items

return Course::where('school_id', self::getAuthSchoolId())->with('lessons')->get()->toArray();

doing dd($courses)

array:2 [▼
  0 => array:13 [▼
    "id" => 3
    "school_id" => 2
    "slug" => "test"
    "title" => "Test course"
    "description" => "Test description!"
    "excerpt" => "Short test"
    "public_description" => "###Test"
    "image_path" => null
    "price" => 25000
    "created_at" => "2018-03-04 21:19:44"
    "updated_at" => "2018-03-04 21:19:44"
    "deleted_at" => null
    "lessons" => array:3 [▼
      0 => array:17 [▶]
      1 => array:17 [▶]
      2 => array:17 [▶]
    ]
  ]
  1 => array:13 [▶]
]

and running

<?php foreach ($courses as $course) {
          $course->id;

       }
       ?>

gives error

Trying to get property of non-object
