    $.post('php/cargarPreguntas.php', {}, function(datos, textStatus, xhr) {

        var tmpIdx  = 0;
        var tds     = '';

        $.each(datos, function(indice, val) {
            if (tmpIdx !== val.idCat){
                if (tmpIdx !== 0){
                    tds += '</div>' 
                }
                tmpIdx = val.idCat;
                tds += '<h3 title="' + val.catDesLar + '">' + val.catDesCor + '</h3>';

                tds += '<div>';
            }
            tds += '</br>';
            tds += '<div class="row">';
                tds += '<div class="col-sm-2">';
                    tds += '<h8>' + val.idCat + '.' + val.idPre + '</h8>';
                tds += '</div>';
            tds += '</br>';
                tds += '<div class="col-sm-6">';
                    tds += '<h9 title="' + val.preDescLar + '">' + val.preDesCor + '</h9>';
