Use a mouse-over transparent popup menu for the navigation

I would like to use a mouse-over transparent popup menu for the navigation to replace the default navigation links that allow to switch from one form view to another. Do you have any suggestion for how to implement it?

The ‘Panel > Popup Panel’ control should work for that.

Eric,

Can you elaborate it a little more? I am under an impression the best result will be like in the sample of http://communities.softwareag.com/ecosystem/communities/public/Developer/webmethods/tutorials/CAF/RoleBasedNav/RoleBasedNavigation_ViewLiveSample.html#1098560. Can I design my own mouseover transparent popup menu to replace the navigation links?
