I cannot find a way to create a picker where the components are grouped and aligned with titles. My picker needs to allow multiple types of information to be selected, some of it is composite numbers (i.e. select digits for thousands, hundreds, tens and units). I have mocked it up here.
I need a done button, the titles should be centred over the groups and I need a decent space (say 10 pixels) between the titles and the picker data. I have been doing lots of reading on pickers and understand how to use them, but I am really struggling to find a simple way to format them into groups.
