如何输入一个数据，其他数据自动完成？

I wonder how to apply one data and the other data is automatically completed to the code.

I've tried pluck() method and I just get value like the code bellow :

this is the controller

public function __construct(PKLRepository $pKLRepo)
{
    $this->pKLRepository = $pKLRepo;
    $this->data = Siswa::pluck('nis','id');
}

public function create()
{
    return view('p_k_l_s.create')
            ->with('data', $this->data);
}

create.blade.php

<div class="form-group col-sm-6">
{!! Form::label('nis', 'NIS:') !!}
{!! Form::select('nis', $data, null, ['class' => 'form-control']) !!}
</div>

<!-- Name Field -->
<div class="form-group col-sm-6">
    {!! Form::label('name', 'Nama:') !!}
    {!! Form::text('name', null,['class' => 'form-control']) !!}
</div>

<!-- Academic Year Field -->
<div class="form-group col-sm-12 col-lg-12">
    {!! Form::label('academic_year', 'Tahun Akademik:') !!}
    {!! Form::text('academic_year', null, ['class' => 'form-control']) 
     !!}
</div>

the code above just return nis value, but I want to autocompleted the form if I select one of the values from nis. Any suggest?
