According to this http://community.jboss.org/message/583307,
there should be a expanded-property for rich:panelMenu in RF4. However, I cannot find it.
How can I set up rich:panelMenu to be expanded by default.
In RF3, I can set expanded="true", but in RF4, this property does not exist.
(By the way: I even cannot find a reasonable description of the meaning for all propertys of rf-properties. I have already created a issue https://issues.jboss.org/browse/RF-11785)
How can someone work with these components without knowing what each property of a component is for?
