There is an issue with the menu system when it drop down over a product image.
I have a dropdown menu using the Lunar Menu system, please follow these steps and you will see what I mean.
1. Click on your boxed version demo
2. Click into any product
3. Now hover the mouse over the menu ‘Women’ and try to select a category
You will see that the menu disappears and the image zooms in, so you can’t actually select anything from the menu when it hovers over a product image.
I have tested this in Firefox, Crome and Safari (mac)
