Click-to-Action (C2A) is a feature of IBM® WebSphere® Portal that allows data to be transferred and shared among multiple WebSphere Application Server portlets via UI elements such as drop-down menus.
Development of portlets containing C2A functionality using IBM WebSphere Portlet Factory Designer is not much different than developing any other kind of portlet using WebSphere Portlet Factory Designer.
