Interface IListgroup

All Superinterfaces:

IChildable<IListgroup,IListcell<IAnyGroup>>, IComponent<IListgroup>, IHtmlBasedComponent<IListgroup>, IListboxComposite<IListgroup>, IListgroupChild<IListgroup>, IListitemBase<IListgroup>, IMeshComposite<IListgroup>, IXulElement<IListgroup>

public interface IListgroup
extends IListgroupChild<IListgroup>

Immutable Listgroup component

Adds the ability for single level grouping to the Listbox.

Support @Action

Name	Action Type
onOpen	ActionData: OpenData Denotes user has opened or closed a component. It is useful to implement load-on-demand by listening to the onOpen action, and creating components when the first time the component is opened.
