Change vertical language selector in the configuration panel of Atahualpa?

Hi,
I added in the site I am doing a WPML plugin.
I have the language selector already in a header widget I created for that.
The plugin gives me only the option of a vertical language selector.

I asked them How can I change the vertical language selector to a horizontal one?
Here the answer:

ANSWER: Copy the following code into your theme's functions.php file.

function language_selector(){
$languages = icl_get_languages('skip_missing=0&orderby=code');
if(!empty($languages)){
foreach($languages as $l){
if(!$l['active']) echo '<a href="'.$l['url'].'">';
echo '<img src="'.$l['country_flag_url'].'" height="12" alt="'.$l['language_code'].'" width="18" style="margin:1px; border:1px solid #333;"/> '.$l['native_name'];
if(!$l['active']) echo '</a>';
}
}
}

Then give the call to function language_selector() wherever you want to make it appear in header.php file

<?php language_selector(); ?>

MY question is:
There is any way I can managed to get a horizontal language selector in my header doing that in the configuration panel of Atahualpa, without changing code in PHP.

Any help will be really appreciated,
