I assume you are developing a Desktop style web application. It might work on drilldown too, but I haven't tested it. You can do the following if you want to add a header panel with some info, logos and stuff over the command bar on your WebApp.src:

1. Create a cWebPanel inside oWebApp object in WebApp.src (let us call it Level1).
2. Create another panel inside Level1 and its peRegion as prTop (let us call it Level2).
3. Move oCommandBar object inside Level1.
4. Assign oCommandBar peRegion as prCenter.
5. Begin adding components to Level2. You can also add another panel like Level2 inside Level1 and set its region as prBottom and use it as a toolbar... Whatever you want.

That is what we do, I don't know if there is anything better or a simpler way to do it, but it works. I would like to see more ideas if someone uses another method to create headers!
