Dear Mits, thanks for your reply.
I am afraid I didn't express myself clearly. I mean, I put much template files to Repository > Data Dictionary > Note Template, while creating a file based on a template, I will see many template files in a long list. here I hope to the classification happened, for example, I hope these template files can be classified into several folders, when I select the folder, then the related template files displayed.
I tried to create the folders in Repository > Data Dictionary > Note Template folder, and put the related template files in, but those template files won't appear while I create a file from a template.
Anyway thanks for your help!
