Silverlight dropdown menu in a html page?

I'm not too familiar with silverlight, so I'm pretty sure I am asking a basic question.

Is it possible to have a silverlight dropdown menu (like superfish, or so-called dhtml menus) in a web page that will ;

1. not use more space in the page than the first level
2. wi开发者_Python百科ll go over html content when we expand it.

I guess that Silverlight has to be displayed inside a certain "canvas" like flash, so the silverlight menu has to be either :

• as big as the fully expanded menu can be -- with the possibility to display html over it (using css?) and make sure that the expanded items goes on top of html ==> That seems not really easy!
• as small as the first level of menu items -- means that silverlight has to get out of the canvas to display menu items ==> Is that even possible?

I know that this may sound ridiculous, but the project is to modernize the portal around sql server reporting services using silverlight in a sharepoint webpart. There's no possibility to change the setup, I just want to know if that could be achieved using silverlight. If it can't, we will fall back to superfish.

Thanks!

It is possible. Silverlight plugin should be set to windowless, so its content can overlap with html. Because Silverlight can not draw outside of its own surface you would have to make as large as biggest menu element or you could resize Silverlight container dynamically through javascript bridge.
