Submenus in ContextMenu

Hi!

I am a complete newbie in .NET C# and SDL Trados APIs, so sorry for my ignorance in advance. :)

I was able to add a new menu item into context menu in Studio editor for calling my own Action. Since I want to maintain some user-specific (plugin) settings, I created a form to save some connection information into Settings.Default.... Now I want to be able to open the settings form anytime and the best place (for me) seems to be from a submenu of my plugin in ContextMenu.

So, please, could you tell me how to add such a subitem into the context menu or where is a better place to put a button to open the settings form?

 

And be prepared, other questions will follow soon. :)

And thanks for the great opportunity to write plugins for SDL Trados with the APIs!
