Dynamic Cascading Drop-Down List

Hi support,

I followed the below link to create a Dynamic Drop-Down List.

I succeed with the first method by grouping but failed with the second method.by Options Binder.

I tired with the example from the link, the Options Binder could not link up the 2 select box "Type of leave" and "Category".

Whatever I choose in the "Type of leave" box, nothing would shows up in the "Category" box right away.

Also, I found another link which may able to do what I want,

But I could not find the options under Options Binder, is that a Enterprise+Edition+Features?

Thanks a million.

Gilbert
