Need option masonry_container_style

Hi, i need for my custom implementation of masonry, the option masonry_container_style to set {position: absolute}.

My code is something like that right now in template.php

$container = '.container';
$options['masonry_item_selector'] = '.subitem';
$options['masonry_column_width'] = 50;
this is what i need ------> $options['masonry_container_style']= "{position: 'absolute'}"; <-------
masonry_apply($container, $options);

I have tried with no success the following:

• $options['masonry_container_style']= "{position: 'absolute'}";
• $options['masonry_container_style']= "position: 'absolute'";
• $options['masonry_container_style']['position']= "absolute";

Is this possible ?
