Populate dropdown with relation data in Laravel

Question

I have a relation of category and sub category, I'm getting category data with related sub category using this query:

$data=Category::with('subcategory')->find($categoryID);

now i' getting category with related sub categories, that sub categories array i want to populate in the dropdown, Is there any way so that i can populate sub categories data without looping.

 {{ Form::select('subcategory[]',$subcat,[],['class'=>'form-control','multiple'=>true]) }}

In your controller you will need fetch sub categories ids like so

$sub_categories = $data->subcategory()->pluck('id')->toArray();

now you will pass $sub_categories to your view and in your form select

{{ Form::select('subcategory[]',$sub_categories,[],['class'=>'form-control','multiple'=>true]) }}
