Separated category field?

[sangsub.kim]

I want to make the field like the below.

When I choose Category 1 as "A"

Category2 only display  a-1 and a-2

also If I choose Category 1 as "B"

Category 2 only display b-1 and b-2

Finally I want to display multi choice like a-2,  and b-1

( We can see this from shopping mall site)

How can I make it?

Try adding a "cascading select list" to your project.  I think it allows for exactly what you're describing.

OK I will check it as your advice.
