On the live demo site for hiero, when viewed on a mobile device or a desktop with the browser window at a small width, the drop-down menu is broken. It works fine for the level 1 menu, but when trying to view the 2nd level menu, it does not display properly. Instead, it half-appears inside of the level 1 drown-down portion.
I would love to use this theme if this problem was fixed. Thanks!
