wow - that is fantastic! Many many thanks for that.

One final question.....! Is there anyway that the expanded items (such as training day one etc) and the sub items (document one etc) can be in line with the first list?

ie (when expanded)
Training
Training Day One
Document One
Document Two
Document Three
Document Four
Training Day Two

etc

instead of the large margin on the left that the lists create?

Thanks again!
