Field should be formatted for SSN.
9 numerical digits only + 2 dashes (XXX-XX-XXXX)
<div class="col-md-6" data-number="0" id="amdCorrSSNcont">
<label for="correctSSN">Correct SSN</label>
<input type="text" placeholder="XXX-XX-XXXX" class="form-control" id="correctSSN">
</div>
How can I format the field ?
Using RegEx is probably the best way. Make sure field max-length is correct, and use the pattern match for ###-##-####
^([0-9]{3}[-]{1}[0-9]{2}[-]{1}[0-9]{4})
