Tree View Widget and Snippet?

I was able to configure the tree view widget to be able to show the hierarchy of the different objects. Another functionality I wanted is that when I click on a certain object in the tree view, I'd like for details of the object to show up on the right hand side. Now I understand this kind of functionality was achieved with the help of the form loader widget in Mendix 4. How do we achieve this now? I am trying to use snippets but I am still not sure of how to do this? Could someone please explain to me how this can be achieved?

Why not use a split pane function or create a master detail layout page? By using a selector association preferably set on the current user viewing the tree this should be doable.
