What you are looking for is a "HierarchicalDataTemplate" to use with your collection. I agree with one of the commenters that your question is too general and feels like you need to take your own stab at this question first, but I'll point you in the right direction of a sample: http://karlshifflett.wordpress.com/2007/11/10/over-reaction-to-a-simple-wpf-explorer-tree/

Hope this helps.
