[Zope] can I stop tree moving page view

Another tree difficulty: I have a tree widget in a page. When branches are expanded or collapsed the view you get in the browser moves. Now I know this is somewhat unavoidable but can anyone think of a way to limit the effect for example some way of making the text above the newly-expanded bit stay still and just re-rendering that below instead of shifting everything around?
