public class ERXOptGroupPopupButton
extends ERXPatcher.DynamicElementsPatches.PopUpButton

Quick hack at extending WOPopUpButton to use HTML 4 optgroups. It adds two bindings: group and label. group is required. When this value changes, a new optgroup is created. label is optional. This is used as the label for an option group. If label is not bound, an empty string is used as the option group label. Also adds bindings to style or disable individual items.

Bindings

group	Object, required - keyPath to value that changes when the group of options changes
label	String, optional - String used as label for an option group
itemClass,	optional - String CSS class name for this item, browser support is inconsistent
itemStyle,	optional - String CSS style for this item, browser support is inconsistent
itemDisabled,	optional - boolean indicating if the current item should be disabled or not. Browser support is inconsistent. Be prepared to handle the case where the user selects a disabled option!
