Have a lot of values in the left navigation, such as long models or sizes list? Due to Magento Layered Navigation pro you can easily hide them until a customer selects some values in the parent attribute. For example, you can choose 'Shoe size' filter to be displayed only when 'Versace' or 'Gucci' is selected in the 'Brands' filter.
