How effective would other professionals rate a hamburger menu on its own. Is it necessary to have a menu which is 100% visible and doesn’t need a click to be shown. I intend on using the answers here to determine my future projects.
Please note I am talking about mobile / tablet sites. I believe menus shouldn’t be hidden in desktop sites.
Here is an example of a mockup I made for my site which is in construction.
I think the hambuerger menu is recognizable by the vast majority of users nowadays, when in the right context.
In your example, I do not think it is obvious. I usually expect to see the icon for expanding a menu, whether it be a hamburger icon, three vertical dots or a “menu” link on the top right edge of the screen, possibly the left top. But there in the middle it makes me think it’s a control to drag/resize the top part. Adding the word “menu” or making it look more clickable would certainly also help.
