$categories is a collection (array of objects) and you're trying to add it as a integer in your form select. if you want total number of categories then use $categories->count() – Nehal Hasnayeen
i actully use pluck('id',name) for $categories and want to have list of category for select – hussain

you can do this:

<select>
    <option value=0 > زیر مجموعه مورد نظر را انتخاب کنید  </option>
    @foreach($categories as $category)
       {
        <option value={{$category->id}} >  {{$category->name}} </option>
        }
</select>
