In mobile application, If I have a form or frame and it contains a unimSelect, the form/frame will be scrolled up if the UnimSelect is dropped down. The form/frame will stay at that condition even though the unimSelect has been backed to normal state (please see attachment).
I tested by using iPhone 5 and 7 with browser safari, chrome and opera. All have the same result.
But it's not happened in Android.
