The Input Mask property is available for Text fields and can be used to constrain what users type in a Field when adding records. It can be used to make sure that users enter certain digits or letters.
When adding Records, as users type in the field that has an Input Mask, the data entered will automatically get validated and the field will turn red if the data entered do not match the Input Mask and green if they do.
Input Masks can be useful if you have a field with administrative codes, for example or if you want to customise a Serial Number field using a Text field and you want the text to have a specific format.
The following table shows the characters that can be used to create an Input Mask and their explanation.
|0||User must enter one digit (0 to 9)
|00||User must enter two digits (0 to 9)
|L||User must enter a letter|
|LL||User must enter two letters
|A||User must enter a letter or a digit
|\||Character immediately following will be displayed literally
