Masked field

A masked field is an enhanced input field that improves readability by providing visual and non-visual cues to a user about the expected value.

Masked field

<TextField mask={...}>

A Mask component renders a controlled input field that applies formatting to the input value when the field is blurred.

Passing a mask prop into the TextField component with a valid value will enable formatting to occur when the field is blurred. To "unmask" the value, you can import and call the unmaskValue method.
