iOS recognises links in the format
I'd like to add such a link as a 'Custom Link' to a wp_nav_menu that I'm only targeting at iOS (more specifically, only iPhones) but entering "tel:07954000000" in the URL amounts to nothing (it gets wiped when I try to save the menu).
I suppose these links have to start "http://" (or similar) to work; I wonder if anyone knows of a way in which I could make this work (short of hard coding it in).
Basically, I'd like a link on my wp_nav_menu which, when tapped, will make a phone call.
All suggestions much appreciated.
