Validate select with the jquery.validate plugin

Question

I am not able to validate the html select with the jquery plugin..

The select to be validated would be select class="Uf"

How would you validate this select with jquery.validate?

I’m doing like this

$(document).ready(function () {
    $('#post').validate({ // initialize the plugin
        rules: {
            email: {
                required: true,
                email: true
            },
            nome: {
                required: true,
                minlength: 5
            },
            fantasia: {
                required: true,
                minlength: 5
            },
            cidade: {
                required: true,
                minlength: 5
            },
			uf: {
                required: true
            }
        },
        messages: {
            required: "Campo obrigatório",
            remote: "Please fix this field.",
            email: "Por favor insira um email válido",
            url: "Please enter a valid URL.",
            date: "Please enter a valid date.",
            dateISO: "Please enter a valid date (ISO).",
            number: "Please enter a valid number.",
            digits: "Please enter only digits.",
            equalTo: "Please enter the same value again.",
            maxlength: $.validator.format( "Não insira mais do que {0} caracteres." ),
            minlength: $.validator.format( "Digite pelo menos {0} caracteres." ),
            rangelength: $.validator.format( "Please enter a value between {0} and {1} characters long." ),
            range: $.validator.format( "Please enter a value between {0} and {1}." ),
            max: $.validator.format( "Please enter a value less than or equal to {0}." ),
            min: $.validator.format( "Please enter a value greater than or equal to {0}." ),
            step: $.validator.format( "Please enter a multiple of {0}." )
        },
        submitHandler: function (form) { // for demo
            $(".resultado_form_lojista").html('<p class="resultado_form_p">Enviando...</p>');
            var form = $('#post');
            $.ajax({
                url: 'envia_form_lojista.php',
                type: 'POST',
                data: form.serialize()
            })
                .done(function(data){
                    $('.resultado_form_lojista').fadeOut('slow', function(){
                        $('.resultado_form_lojista').fadeIn('slow').html(data);
                    });
                })
                .fail(function(){
                    alert('Ajax Submit Failed ...');
                });
            return false; // for demo
        }
    });
});
