does anyone know how I can group the files * .OTF not keep repeating the list ? For example , group all "Helvetica CE" for a single line, and its variants to display the top menu.

Get hold of a font editor and modify the fonts' internal names, but....

+ You are likely breaking the EULA and voids your license to use the fonts
+ You can only group Regular, Bold, Italic and Bold Italic styles in Windows (I am assuming you are in Windows.) You are going to have a big problem in Windows if you group into one family all those Heveticas. The only exceptions are those Adobe apps.

If you want to risk it... change the family name to Hevetica CE and the style name to Bold Narrow Oblique for Hevetica CE Bold Narrow Oblique and do the same for the rest of the Hevetica CEs. You might have to check some boxes along the way. How you will actually do it will depend on the font editor that you willare going to use.
