Have you ever noticed those three horizontal lines on the top of the website or app? Yes, that is a hamburger menu, which collapses on clicking. The hamburger menu is without a doubt one of the most enduringly popular navigation bars. As it saves space, and provides a neat looking UX. That’s the reason it is designer’s and businesses’ favorite. The hamburger menu found its existence in the design world, when in the ‘80s interaction designer Norm Cox designed it as part of the interface for the Xerox Star. However, this incredible navigation bar found its recognition in the year 2009, mobile apps became a household stuff, and people realized the worth of it. The very limited screen space it consumes on phone screens make this bar an engaging space-saving tool.
