Hamburger Menus
The hamburger refers to an icon used to represent a website menu. The icon consists of three short horizontal lines stacked vertically.  This minimal navigation also sometimes called a hotdog menu or a three-line menu.
This menu takes up less screen space than traditional devices and has, therefore, become a popular navigation element on mobile devices.
Desktop & Mobile Support
Good Gallery supports the hamburger menu on both desktop and mobile devices. The display of hamburger icons is controlled by your system settings. It’s displayed by default on mobile devices and is disabled by default on desktop devices.
