I'm using Foundation and have a series of sections at height: 100%.
I'm using the off-canvas menu but it's only matching the height of the first section / the viewport. So once I scroll, the off-canvas menu is no longer aligned to the height of the viewport.
It's a similar issue to Foundation 5 off-canvas full height of device.
I'm ending up with this:
After scrolling down to next section
I think it can be solved by to adding position: fixed to left-off-canvas-menu, but that's not working.
It's driving me mad.
