If I am not wrong you want to select the date from the calendar using keyboard right. It seems that no keyboard event-listeners are configured on that when saw in DOM to open the calendar. But once opened you can control using keyboard. I think dropdown would be more suitable where you can move from one to another using tab key.
Thats right Kakul. I have suggested this approach but the business isn't comfortable with this.This is the same approach thats used in the Accessibility framework in Pega.Let me try to convince the business :)
Is there a keyboard event listener added for calendar control in Pega 7.3?
