DateField Mask

There is no auto correct option as of now, can you please elaborate your requirement?

AFAIK, this is not possible using datefield as of now.

You could do that using a text field. Then parse the entered values into a date inside the saveInto.

So as [mention:a11f77a729fb4db2af76b09948583328:e9ed411860ed4f2ba0265705b8793d05] says you could use a text field, apply the necessary validations, and then construct the date by extracting the day/month/year components and concatenating them into the relevant format before saving into the target variable.

But I have to ask why you feel it necessary to go to all that trouble. The data field provides all of the necessary validation, it'll adjust accordingly to different locales (e.g. mm/dd/yyyy for the US, dd/mm/yyyy for the UK), has a date picker, all of which costs the user two extra key strokes to include the "/" separator.

a!localVariables(
  local!a:02022024,
 {
   a!textField(
  label: "Date",
  value: text(local!a, "dd/mm/yyyy")
)
}
)

You can try like that but not a good practice.
