Menu problem

[Robert Presender]

Hi,
Need help again re menus.  Using OS 10.2.1,  1.1.1 r2, 1.5A7r1

I have a menubar with several btn menus as pulldown:  one of the menus 
has several items:
New
Trans
-
Sort
-

I would like to have the Sort item to be cascading(?) like:
-
Sort  (arrow symbol)      By Date
                                           By Event
  -

Tried to follow the info in About Menus but have had no success.  Tried 
tabbing Sort to no avail when in properties.  Checked custom to make 
sure Tab was true not false.

Will appreciate help in this matter.  TIA

Regards ... Bob
