ActionMenu should start with a Closed state

[thsaravana]

Currently when you add an ActionMenu, the menu is opened at start. We don't want this behavior. We want it to be closed at start, and then when the user calls open(), it should open.

It would be great if we have control over the state, so that we can tell the ActionMenu whether it should start as opened or closed. But we can have a separate task for that.
