Premium Version

Before I purchased this plugin I reviewed the Preview here:
https://yithemes.com/themes/plugins/yith-woocommerce-category-accordion/

There are no setup options for getting the menu to open horizontal as demonstrated in the preview. Instead it simply drops down over the footer and off the page which is pretty ridiculous. Due to the large number of Parent categories I have with subcategories I need the menu to open horizontally like the preview demonstrates, how is this accomplished?

Thank you
