I’m having a similar issue. This is across iPad, iPhone and Android phones. The secondary menu always loads open and can’t be closed.
The issue seems to be how the pixel size is being defined for the device via the viewport meta name. For the iPad, I resolved it using the following code:<meta name=’viewport’ content=’width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no’ />
The expanded menu issue on smartphones still is happening. The website is: http://www.cornerwines.com
Any help to resolve it is appreciated.
