I added a custom validation method to jQuery Validation such as:

$.validator.addMethod('myregex', function (value) {
    return /\d/.test(value);
}, 'Please enter a valid input.');

Note that I know there is a build in number check. That is just an example, I actually want to use more custom regex validators.

The problem is that now the field form is always required. Even if I set the value required to false in the code such as:

   $("form[name='my-form']").validate({
        // Specify validation rules
        rules: {
            form-field: {
                required: false,
                myregex: true
            },

I want my regex to check if the data entered on a field is valid, but not force the field to be completed as its optional.
