select option popup opening upwards

[violabg]

I'm using the mdl-select with cascading selects.
I have 3 select in a vertical layout.
I have a problem when I select the second one. It has a long list (10 options), so instead of opening down (I guess because it feels there is no space) it opens upward. The problem is that I have e fixed navbar and the list goes under it, so I'm not able to reach and select the first couple of items on the list.
This is happening on iOS safari not on desktop.

Is there a way to always open the option list down?

This would require option in both select and popover like "disable-update-direction" and addingif (this.disableUpdateDirection) return null;atupdateDirection` method head.
