Some questions about drop-down lists with filter function

[Davider]

@Kevin
about #5 code (I made some changes):

I don't need to sort. I deleted the following line of code, but it doesn't work
 

Code:

Copy      Help

x.Sort(3)

demo:

I expect the result:
Type a:
c   1a
b   2a
a   3a
-------------
Type b:
c   1b
b   2b
a   3b    


Macro M8

Code:

;a02b   2a
;a03a   3a
