I'm looking at using the RadMenu in a SharePoint (MOSS) publishing site.  I've followed the white paper and have got the menu integrated with some success using SharePoint Designer to modify my master page.  However the menu does not display/behave the same as the standard ASP.NET menu control does due to the datasource's structure.

For example, my site collection is called 'Intranet' (and this is the top level site) and I have the following sub-sites created beneath it:

• Subsite 1 (with its own subsites or pages)
• Subsite 2 (with its own subsites or pages)
• Subsite 3 (with its own subsites or pages)

Following the white paper, I get a horizontal menu showing only the three subsites on the menu bar, and then their subsites pop-up as drop down menus.  This part is fine, but the Top level site 'Intranet' is missing from the navigation.  This appears to be the same behaviour as seen in the BlueBand.master which the white paper is based on, however I'm wanting to get the same behaviour as can be seen in the default.master where the horizontal menu would show:  Intranet, Subsite 1, Subsite 2, Subsite 3.

Question 1: How can this be achieved?  Note that in SharePoint the 'Intranet' node shown first can be replaced by other sub-sites as you travel deeper into the site hierarchy if you have configured the Navigation for a sub-site to "Display only the navigation items below the current site".

I was able to hack around a bit in SharePoint designer and got the behaviour I was after using two controls.  While this works it does not seem the best solution and I suffer from another problem.  Here is the hack:

I duplicated the PortalSiteMapDataSouce and set the ShowStartingNode = true and then placed two RadMenu's side by side, the first showing just one level (this exposes the 'Intranet' node I was missing) and the second showing the Subsite 1 to 3 menu nodes next to it.  With a bit of CSS tweaking, to the user it looks like one menu bar but importantly all four menu items are present.

The problem I get with this however is that when the number of menu items shown on the menu bar is wider than the browser window, the excess menu items wrap around below on to the next line.  If I set a width on the RadMenu's I can limit the effect so it cuts them off instead of wrapping around to the next line - my preferred behaviour.  However I do not know what width to set as the website uses a liquid layout.  Putting in width="100%" forces the second RadMenu to be pushed to the next line and anything less will cause a gap or a push to the next line depending upon the size of the first RadMenu to it's left.

Also, I can use a CSS style to set overflow to hidden, but then the drop down menus are also hidden.  So far I can not see how to resolve this problem.

Question 2: Is there any other way, using the hack above, to stop the second RadMenu's items from wrapping around on to the second line when the browser window is not wide enough to display them all on a single line?

You may probably ask why I don't just do the following:

Where I set the ShowStartingNode to true, then use just one RadMenu to display it?  If you try this, the RadMenu will display just one menu item on the horizontal bar, 'Intranet', and this will have the three subsites as drop down menus.

I've been looking at this all day and I fear I am missing the obvious, case of wood and trees. :)  Can you help?
