Minimal Mobile Form

This UX concept provides minimalistic design solution for two of the most common frustrations I come across in mobile forms.

1. Form field error management
It takes up a lot of real estate and sometimes it is not clear what the user should do. How about a hidden modal to minimize the space taken and brief of cause of error and an immediate suggestion or call to action?

2. Quick date selection.
While date selection in travel websites are user friendly, the fields to choose date of birth or other past dates have to be designed differently. A few form offer a dropdown where the user has to scroll to find the year. How about a grid that can pack a lot of years? The scroll time is reduced and the user will be able to choose a year with just a single tap.
