Select list Size value not working iOS

I’d like my Select list to be shown open via the Size value. Such as Size=8. So I can see 8 items in the list. However, this Size value is ignored in iOS because the Select is always shown closed up.

Is there any way I can get the list to display open, and if not, is there another way I can achieve a similar ‘look’ using another kind of element?

Thank you...
