JEA amenities layout add custom css style - php

Question

I was looking at the code and just don't get how to add a custom CSS class to ul tag?
<?php if (!empty($this->row->amenities)): ?>
<h3><?php echo JText::_('COM_JEA_AMENITIES')?> :</h3>
<?php echo JHtml::_('amenities.bindList', $this->row->amenities, 'ul') ?>
<?php endif ?>
Which generates:
<h3>Amenities</h3>
<ul>
<li></li>
<li></li>
<li></li>
etc.
</ul>
I need:
<h3>Amenities</h3>
<ul class="check">
<li></li>
<li></li>
<li></li>
etc.
</ul>
I'm sure, it should be something simple.

The Source of the function is -
static public function bindList($value=0, $format='raw')
{
if (is_string($value) && !empty($value)) {
$ids = explode('-' , $value);
} elseif (empty($value)) {
$ids = array();
} else {
JArrayHelper::toInteger($value);
$ids = $value;
}
$html = '';
$amenities = self::getAmenities();
$items = array();
foreach ($amenities as $row) {
if (in_array($row->id, $ids)) {
if ($format == 'ul'){
$items[] = "<li>{$row->value}</li>\n";
} else {
$items[] = $row->value;
}
}
}
if ($format == 'ul'){
$html = "<ul>\n" . implode("\n", $items) . "</ul>\n";
} else {
$html = implode(', ', $items);
}
return $html;
}
As per the source of the function the way I can see is to replace '<ul>' to '<ul class="check">'
<?php
$html = JHtml::_('amenities.bindList', $this->row->amenities, 'ul');
echo str_replace('<ul>','<ul class="check">',$html);
?>
Or you can call getAmenities function and loop through result and create your own ul and li.
Hope this helps.
