      @foreach($data['categories'] as $category)
        <option value="{{$category->id}}">{{$category->name}}</option>
      @endforeach
    {{Form::submit('submit', array('class'=>'btn btn-lg btn-primary btn-block'))}}
  {{Form::close()}}

Answer 1

Controller:

$data['categories'] = Category::lists('name', 'id');

If you are using the attribute Category model controller:

$data['categories'] = Category::get()->lists('name', 'id');

view:

{{ Form::select('expense_category_id', $data['categories'], null, array('class' => 'form-control') }}

For laravel5.3 use pluck.

$data['categories'] = Category::all()->pluck('name', 'id'); Reference

You can try.
