On tablet (including the iPad), the Parent Menu reacts too quickly to touch.
If the Parent link has a Child Menu, this Child Menu is displayed but the Parent link loads immediately.
So I do not have time to click on any item in the submenu.
It may be necessary to use the first touch to activate only the Child Menu display (sub-menu)
and that the second touch on the same link loads the link.
In the demo of Helix3, with the link BLOG it works well.
