I am developing a mobile webapp in DF20.1 that creates order lines by scanning QR-codes and then entering no of items of the line by the numeric keyboards that pop up. After that is a text line where optional text can be entered on the keyboard that now change to letters. After pressing the forward arrow, the scanning form is focused again.

Then, however, the alphabetic keyboard is still shown hiding the just scanned order line, so the user ha no control if that one is OK. It is possible to hide the keyboard by pressing a hide button, but that takes time. Is there any possibility to hide the keyboard by the program?

The app is primarily developed for a Zebra mobile device as that one has a scanner that is easy to use.
