I've have a drodown menu into my navbar, on the right side. But every time when I click into "Open Menu" button, my design switches to Tablet view. As you can see in this video: http://www.filedropper.com/cast
And also, All the styles that I've created for that Dropdown menu can't be deleted.
Macbook Air 11", Google Chrome 41.0.2272.89 (64-bit)
Anyone knows why?
