Hi,
To fix this issue, please go to file: skin\frontend\default\sns_lunar\less\style.less find with the key ‘.wrap’ and delete the bellow code:

z-index: 0;
&:hover {
	z-index: 1;
}

Similarly, please go to file: skin\frontend\default\sns_lunar\less\core\custommenu.less find with the key ‘#sns_custommenu’ and delete the bellow code:
li:hover {z-index: 1;}

Thanks!
