How to make laravel display grouped values

I'm developing a question answer app using laravel, I want to display all answers under each question for that particular question. The problem I'm facing is I'm unable to alter the view to display answer under the respective question, since there is no way to match ID's in laravel views!

My view code:

@section('list-questions-answers')
    <ul>
        @foreach($listQuestions as $q)
            <li><a href=""></a></li>
            @foreach($listAnswers as $a)
                <ul>
                    <li></li>
                </ul>
            @endforeach
        @endforeach
    </ul>
@endsection

Answer's model

public function User()
{
    return $this->belongsTo('App\User');
}
public function questions()
{
    return $this->belongsTo('App\questions','answer_id');
}
public function scopefetchAnswers($query)
{
    return $query->select('answer')->where('people_id','<>',Auth::id())->get();
}

Everything is display on the dashboard.blade.php, which runs on dashboard controller

class Dashboard extends Controller
{
    public function index(){

        $listQuestions=questions::latest('created_at')->fetchQuestions();
        //$listAnswers=answers::groupBy('question_id')->fetchAnswers();
        $listAnswers=answers::fetchAnswers();
        return view('forms.question',compact('listQuestions','listAnswers'));
    }
}

Output I'm getting

Ouput I want
