Adjust CSS for ngOption for android app

Hi, I am currently developing an android app. I am using tag with ng-Options. The problem is the drop down. When user selects an option for first time every thing looks good.
From second time, it scrolls to previous item. User is getting confused thinking where is first item. He always need to scroll up. So my questions are:

  1. Is there any way to always scroll to first index?
  2. Is there any way to adjust height of ng-option?

I tried for 2 hour I am not able to set either. Kindly let me know for any inputs

This is Android primary control , We can’t use css to style it .

Thanks for your reply.

Is there any other way or any other control we can use instead of so that we can display all values? (popup?)

Hello, can some one help me with this?
