<div class="form-group">
            {!! Form::label('Country', 'Country:') !!}
            @foreach($countries::all() as $country)
            {!! Form::select('country', array($country))!!}
            @endforeach

        </div>

<!-- Country Form Input -->
        <div class="form-group">
            {!! Form::label('Country', 'Country:') !!}
            {!! Form::select('country', $country) !!}
        </div>
