[Plugin: Menu] How to set the class attribute in anchors to use a jQuery script

Hello,
Can anyone help me?

I have looked into plugin’s files and I have found these pieces of code that perhaps can be used to do something:

in menu.php on line 106 I have found

private function renderMenuItem($item,$count = 99) {
			$class = $this->getItemClass($item,$count);
			$output = '<li class="' . $class . '"><a class="' . $class . '" href="' . $this->getItemUrl($item) . '">' . esc_html($item['label']) . '</a></li>';
			return $output;
		}

while in views/settings.php on line 36

<td>
	<label><span><?php _e( 'Label' ); ?></span> <input type="text" class="regular-text" name="menu[label][]" value="<?php echo esc_attr($item['label']); ?>" /></label>
	<label><span><?php _e( 'URL' ); ?></span> <input type="text" class="regular-text" name="menu[url][]" value="<?php echo esc_attr($item['url']); ?>" /></label>
	<label><span><?php _e( 'CSS Class' ); ?></span> <input type="text" class="regular-text" name="menu[class][]" value="<?php echo esc_attr($item['class']); ?>" /></label>
</td>

What I have thought is that if we could create a new variable to replace $class in

<a class="' . $class . '" href="' . $this->getItemUrl($item) . '">

then we could add a new input field in settings.php, something like this

<label><span><?php _e( 'A Class' ); ?></span> <input type="text" class="regular-text" name="menu[aclass][]" value="<?php echo esc_attr($item['aclass']); ?>" /></label>

Sorry for my Bad English…
If anyone has understood, can help me understand?

Thanks
