请问下删除时如何获取SELECT中的ID

{!! Form::open(array('route'=>array('groupdel',**?????**),'method'=>"delete")) !!} 

 {!! Form::label('group_name','GroupName:') !!}

 {!! Form::select('group_name',$group_name_lists,null) !!}       

 {!! Form::submit('Submit') !!}

 {!! Form::close() !!}

请问下,删除的时候,问号处,应该如何写?才能得到删除时的ID

非常感谢~

{!! Form::model($foo, ['route' => ['groupdel', $foo->id], 'method' => 'DELETE']) !!}
