Examples and length
Under the chips, Accepts e.g. lists up to three example values, taken from each selected format in turn. Length is determined by the format. means the formats decide what is valid, so Min. Length and Max. Length are not used.
Selected formats show example values and that length follows the format.
What respondents see
The answer is checked when the respondent leaves the field and when the form is submitted. An answer that matches none of the selected formats shows an error that names the expected format:
- Phone number (UK) and Phone number (international): Enter a valid UK or international phone number.
- Postcode (UK): Enter a valid UK postcode.
- NHS number: Enter a valid NHS number.
- IBAN and BIC: Enter a valid IBAN or BIC.
A value that matches none of the selected formats shows an error.
An empty field is not checked against the formats. Turn on Mark as required to make an answer mandatory; an empty field then shows This is a required field.
On a phone, the field works the same way. When all selected formats are phone numbers, the phone keypad opens.
On a phone, the same error appears under the field.
