How to add a Folder inside a Folder ? (non)

Question

I have tried even going directly to the srf file to do the grouping manually.
Bear in mind that I have performed this successfully on an existing SAP folder.  But if I tried doing it on a form i've created with the screen painter the results are simply that all folder items group at the same level.
I've read all the links related to this and come across no real solution.  Is it posible at all?

I can't tell you how to do it using screenpainter/xml, but how to do it in code... might get you in the right direction. I't all about setting the correct pane-levels.
A good example in the Client GUI is the BP Accounting TAB with its general and tax tabs inside... Tabs/folders are just normal items in SAP and the pane-from and to on an item is used to tell the GUI what items are where.
Sample1: CardCode hase panelevel 0-0 (0 being the special panelevel that are always shown)
Sample2: Telephone 1 is in panelevel 1-1 since it is under the general tab
Sample3: The Tax-tab under accounting is on pane 9-10 since it need to be shown when both the Account>General tab-data is visible (9) and it's own tax-data (10)
This is the complete "pane-tree" on BP Master data
0: Header
   1: General
   3: Contact persons
   7: Addresses
   6: Payment Terms
   8: Payment System
   9-10: Accounting
         9: General
         10: Tax
   4: Properties
   5: Remarks
To sum it all up, you will need to set you to and from panes in the correct way to create the nesting of the tabs and on each item-pressed on these tabs you need to change the current panelevel
