Why dropdown menu goes under the background image?

When you hover over the drop down menu goes under the background image of the row. Z-index doesn't help. Where to look?

Probably the z-index thing. Look at all parent elements and pictures and menu

Place section background z-index 0 and the menu z-index of 1
