   textStyle={{fontSize : hp('1.25%')}}
   setOpen={item => this.setState({open : item})}
              />

Answer 1

Dropdown picker is good enough. You can use listItemContainerStyle or dropDownContainerStyle.

listItemContainerStyle compresses all of your elements so they fit in a certain height:

listItemContainerStyle={{ height: hp('5%') }}

dropDownContainerStyle cuts to the height you just tell it to:

dropDownContainerStyle={{ height: hp('5%') }}

Both make the Dropdown Container smaller, you can use the one that works fine for you.
