I am trying to follow some of conditions for date input widget, here are those :

  1. Able to enter values (mm/dd/yyyy) like 1/1/2024 or 11/1/2024 or 11/12/2024. 2.after entering full year there should not be allowed to type anything after that

  3. Whole length must be max 10
  4. / this should not be repeated, if you see above format, like that it should work.
