Laravel Grouping a list of todos into one folder

Please I am trying to group a list of todos by selecting them and grouping them into one link. so when I click on the link I will be able to see all the todos I selected and added to the group. how can I do that? I have been able to add these codes but I do not know how to move forward because I am quite new to laravel. here are my codes

 <tbody>
                @foreach($todos as $todo)
                    <tr>
                        <td><input type="checkbox" name="selected_todos[]" value=""></td>
                        @if($todo->completed)
                            <span><td style="text-decoration:line-through"></td></span>
                        @else
                            <td></td>  
                        @endif     
                        <td></td>

                @endforeach
            </tbody> 

  public function todos()
    {
        return $this->hasMany(TodoList::class);

    }

    public function GroupTodoList()
    {
        return $this->belongsTo(GroupTodoList::class);

    }

and I have not included a controller for the grouping because I do not know how to go about it.

Thank you
