## Interface FormItemBaseStyle

-     public interface FormItemBaseStyle

  This string is the base CSS class name applied to a FormItem (or some part of a form item). See the `formItem styling overview` for more information about styling formItems.

  The specified style name will be modified as the 'state' of the form item changes. Developers should provide appropriately named CSS classes for each stateful style described below:

  - If `FormItem.showPending` is true, when the current value differs from the value that would be restored by a call to `DynamicForm.resetValues()`, this style will have the suffix "Pending" appended to it.
  - If `FormItem.showFocused` is true, when the form item receives focus, this style will have the suffix "Focused" appended to it.
  - If `FormItem.showOver` is true, roll-over will be indicated by appending the suffix "Over" appended to the style name. This applies to the `textBoxStyle` and `controlStyle` only.
  - If `FormItem.showErrorStyle` is true, if the form item has errors, this style will have the suffix "Error" appended to it.
  - If `FormItem.showDisabled` is true, when the form item is disabled, this style will have the suffix "Disabled" appended to it.
  - Finally, if `FormItem.showRTL` is true, when the form item is in RTL mode, this style will have the suffix "RTL" appended to it.
  So for example if the cellStyle for some form item is set to "formCell" and showFocused is true, when the form item receives focus, the form item's cell will have the "formCellFocused" style applied to it.
