Could you give your site url? We will have a check.
Yes, here’s my site: http://www.annateodorczyk.com/
I actually don’t use it as onepage.
I tried it on iOS and sub menus are still not visible.
Because in mobile doesn’t have mouse hover state and it isn’t clickable, so it can’t be visible, add the codes in your custom-css, it will be expanded in the mobile.
@media screen and (max-width: 640px){
.site-nav li#menu-item-69 ul {
display: block;
}
}
I’ve got this same problem at http://redfordtheatre.com/. I added your code to the media.css file, but so no difference in the behavior.
Thanks,
Bob
