How Can I Make Validation Inside Specific Tab

form.validate({
      doNotHideMessage: true, //this option enables to show the error/success messages on tab switch.
      errorElement: 'span', //default input error message container
      errorClass: 'help-block help-block-error', // default input error message class
      focusInvalid: false, // do not focus the last invalid input
      excluded: ':disabled',
