I have an issue with my form and database. I am actually developing a booking form for my business but having issue with storing date of birth. I want to allow users to enter date of birth using three separate dropdowns like "Day, Month & Year". And I want to store All these three dropdown's values in one Database collection field named "Date of Birth" in a format like "01 January 2019".
I tried some basic tricks and codes available in the internet but It didn't worked out.
So I need immediate help. So please help me.
