Woocommerce: Show products filtered by attribute

Question

I want to filter products by attribute in Woocommerce using a checkbox or alternatively a link. If I mark the checkbox or click the link I want get all products that have this attribute.

How can I do this? Which files should I edit?

Edit: Now i need do a query to get all products that have a custom attribute 'demo' in my case.

I'm doing this:

$args = array ( 'meta_query' => array( 
array( 'key' => 'meta_value', 
       'value' => 'demo', 
       'compare' => 'LIKE', ), 
       ), 
);

Whats wrong??

Thanks!
