                    </div>
                  </div>

script:

$(document).ready(function() {
      $('input:radio[name="custom_field[account][1]"]').on("change", function() {
          if (this.checked && this.value == '1') {
              $("#select-custom-field2, #select-custom-field3").show();
              $("#input-custom-field4").hide();
          } if (this.checked && this.value == '2') {
              $("#select-custom-field2, #select-custom-field3").show();
              $("#input-custom-field4").hide();
          } if (this.checked && this.value == '3') {
              $("#input-custom-field4").show();
              $("#select-custom-field2, #select-custom-field3").hide();
          } if (this.checked && this.value == '4') {
              $("#input-custom-field4").show();
              $("#select-custom-field2, #select-custom-field3").hide();
          } if (this.checked && this.value == '5') {
            $("#select-custom-field2, #select-custom-field3").show();
              $("#input-custom-field4").hide();
          }
      });
  });

And the CSS:

  input.form-control.forma {
    display: none;
  }

  select.form-control.forma {
    display: none;
  }
