how do i see only contents of a KM folder in a iview?

I made a KM navigation iview but when i see it through the assigned role i see the

folder hierarchy on the left and on clicking on that i can see contents of the folder.

The problem is I dont want the navigation on the left.

I want a breadcrumb(of KM folders) on the top for navigation,the admin menu(action,folder....) and the folder contents(for which folder headers have been specified by using a layout set).

how can i do this?
