How to use set in expression

[#1]

Hi,

I have one scenario, I have a field named 'Category', it has three values:A,B,C

I have one object, say label, I want to show or hide it based on the Category.

If Category is A or B , it shows.

I know we can use a expression to achieve. But how to use like a set, for example: Category='A,B' ?

You could do:

If(Category='A' or Category='B', 1, 0)

if(Findoneof(Category,'AB')<>0,1,0) should work too
