Append/Pre-append text in Laravel Form selectRange - laravel

Question

When generating a selectRange in Laravel, is it possible to append or pre-append text to the select options label? Like a % sign for instance, so all the labels will read {number}%.
{!! Form::selectRange('number', 1, 99) !!}

There is no such thing in Laravel Collective core. I have created my own utility class which extends from Laravel Collective form builder.
In your blade, you can simply write:
{!! MyCustomForm::selectRange('number', 1, 99, ' %') !!}
This is my custom class which extends from Laravel Collectives Form builder:
<?php
namespace App\Models\Utilities;
use Collective\Html\FormFacade;
class MyCustomForm extends FormFacade
{
/**
* Create a select range field with appending text.
* This function overrides Laravel Collective Form::selectRange()
* function.
*
* #param string $name
* #param string $begin
* #param string $end
* #param string $appended_text
* #param string $selected
* #param array $options
* #return string
*/
public static function selectRange($name, $begin, $end, $appended_text = null, $selected = null, $options = array()){
$html = parent::selectRange($name, $begin, $end, $selected, $options);
$dom = new \DOMDocument();
$dom->loadHTML($html);
$xpath = new \DOMXPath($dom);
$options = $xpath->query("*/select[#name='" . $name . "']/option");
foreach ($options as $option) {
$option->nodeValue = $option->nodeValue . $appended_text;
}
$html = self::innerHTML($dom->documentElement->firstChild);
return $html;
}
/**
* This function removes HTML DOCTYPE, html tag and body tag from the
* generated DOM HTML.
*
* #param DOMNode $node
* #return string
*/
public static function innerHTML($node){
$doc = new \DOMDocument();
foreach ($node->childNodes as $child)
$doc->appendChild($doc->importNode($child, true));
return $doc->saveHTML();
}
}
Let me know if there is still something vague.
