ShowMenu: based on folder and textfiles

[r0n]

Is it possible the script could be modified to alllow subfolders also get an ID, this way I also can assign an icon to the subfolder.

Currently:
 

Code:

Copy      Help

 >sub_menu    <=========== NO ID
     8 Normal2
     <

What I request:
 

Code:

Copy      Help

 >7 sub_menu     <=========== WITH ID
     8 Normal2
     <

I did several attempts but I can't get the incremental numbering right.
