eclipse java editor view

I pressed right mouse button and accidentally selected SOMETHING which I cannot revert anymore. Now I have a small panel on top of my editor which shows a very detailed project layout (begins with project name and goes down till method declarations). I don't want that there. How do I remove it?
Please help! Thank you!
Edit: the panel seems to represent the type hierarchy of my project.
That is very simple.. 'Undo ' the breadcrumb option
