I already tried other suggestions/codes around the net to change this Navigation menu background/hover background but still no luck. Hope someone can help me. TIA!
For dropdown background color you can go to Appearance >> Theme Options >> Basic settings >> Custom CSS >> Here you can add the below code with your color code.
.header .header-inner .nav ul li:hover > ul{background-color:#f30;}
Also as we have check the project image and it looks fine.
Old post but I also have the sub-menus problem.
Sub menus are not aligned with the menu and when I try to move the muse over a submenu, the dropdown box disappears.
