+I'd like to create a collapsable tree with a map, eg
+
+* top level item
+
+* * second level item1
+
+* * * content 1
+
+* * * content 2
+
+* * * content 3
+
+* * second level item2
+
+* * second level item3
+
+
+but I can't work out how to specify "all items at this level, and all directories at ../ and all the other directories to the root
+
+any ideas?
