I am trying a drop down list in P10 is a native iOS application.

It is not behaving as I expected.

First of all, I am getting a drop down list like I would expect in a web page and not on iOS. Here is a screen shot: 

Instead of this style:

Is there a way to switch this second more native style? (I hope so.)

Also, with the first style, I notice the performance is very slow to refresh the list when I scroll? When I scroll with my thumb, the list goes completely blank and then a few tenths later it finally refreshes. But it is not very acceptable from a usability standpoint.

Thanks for any ideas,
