Cacti Overlapping Menus

Could someone please fix this issue? I love Cacti’s simple layout, but it doesn’t always work well on cellular devices. Maybe it’s time to add the responsive menu found on some other themes.

See how the main menu overlaps with the language menu on the screenshot below. At the very least, the language menu could be lowered. Ideally, the main menu could be replaced with the responsive side menu found in Antimatter and other similar themes.
