Dynamic Form Option

[afancy]

Hi,

I want to create PostgreSQL with the dynamic option., eg.,
For the following SQL statement with the dynamic input in userID. By this
option, I could show the information of a single users if  I choose one of
them. However, I want to show ALL of the users if I select the first option
ALL. But, now the dynamic form does not support it. May I ask which file I
could some changes? Thanks!

SELECT * FROM user WHERE userID=${User:=-1,-1(All)|1(Jonh
Smith)|2(Harry)|2(Rose)};
