you can try in_array()
https://www.w3schools.com/php/func_array_in_array.asp

<select name="category[]" id="categories" class="js-example-basic-single form-control" multiple>
    @foreach ($category as $element)
    <option value=" {{$element->id}}}" {{  in_array($element->id ,old("category",[]) ? "selected":"") }}>
        {{$element->name}}
    </option>
    @endforeach
</select>

You could try the following code:

<select name="category[]" id="categories" class="js-example-basic-single form-control"multiple>
    @foreach ($category as $element)
      <option value=" {{$element->id}} " {{ (collect(old('category'))->contains($element->id)) ? 'selected':'' }}>{{ $element->name }}</option>
    @endforeach
    
</select>

The variable is not named category[] on the server side, that is just notation to turn it into an array; it is named category.

As Kamlesh Paul has stated you can use in_array to check against the possible values of the old input array:

{{ in_array($element->id, (array) old('category', [])) ? "selected" : "" }}
