i can get my category and its infinit sub category but i dont know how to show them in a slect option tag in this state: (i just want to show a subcategory (and its infinit sub category) belong to its parent in a blade)

categories

cloth
 -Men
  --Tshirt

 -Women 
  --Tshirt

here is my Category Model Method code

public function subcategories()
    {
        return $this->hasMany(Category::class, 'parent_id');
    }

here is my migrations

$table->id();
            $table->string('title');
            $table->string('slug');

            $table->foreignId('parent_id')
                  ->nullable()
                  ->constrained('categories')
                  ->cascadeOnDelete()
                  ->cascadeOnUpdate();

here is my index.blade.php view

<select
class="form-select @error('parent') is-ivalid @enderror"
required="">
<option selected="" value="0">None</option>
@foreach($categories as $category)
    @if($category->{'parent_id'} === null)
        <option
            value="{{$category->{'id'} }}">
            {{$category->{'title'} }}
        </option>
            @if(count($category->subcategories ))
                @include('admin.layouts.partials.subcategory' , ['sub'=>$category->subcategories])
            @endif

    @endif
@endforeach
</select>

here is my partials subcategory blade

@foreach($sub as $child)
    <option value="{{$child->{'id'} }}">
        {{$child->{'title'} }}
    </option>

    @if(count($child->subcategories))
        @include('admin.layouts.partials.subcategory' , ['sub'=>$child->subcategories])
    @endif
@endforeach
