Did you have any success with this? I'm struggling with the same problem. I can create the 2-level menu OK, but the top level loses its selection as soon as the user clicks on a sub-menu. One get-around is to use a MultiView panel, so that each sub-page is actually just a part of the selected page, but that won't do it for me as I want to track page-viewing stats.

I don't know if you're still struggling with this, but I recently came across this post, which has solved the problem for me.

Hey rfurdzik

I was looking for exactly this through CSSAdapters and fortunate to have his this post.

Do you have the latest CSS of the code that you have for the 2 tier menu? I just got the post got ended abrubtly or may be with long code posted, I miss the recent one?

Pl post the recent one

I have developed the code and have it on my site http://www.zikbay.com. It is pure CSS ASP.NET menu with asp menu control.... I use it for commercial application but we could discuss if you are interested to use it. It reads web.sitemap file... Please contact me.

This is what I am looking for, can you provide the sample code? Thanks in Advance
