Custom LOV based on two inputs in Value sets

Summary:

Hi All,

We have a requirement where we have to create 3 DFFs which will have LOVs depends on each other.

These values are custom ones which we have to create through manage values in Value Sets.

Eg:

DFF 1 ( Emp Category - this will have 1,2,3,4)

DFF 2 (Emp Sub Category - this is dependent on Emp Category and if we select 1 in employee category the the LOV for this sub category is A ,B and c and if we select 2 from above DFF then the values will be D,E and F)

DFF 3(Emp Sb category 2 - this is dependent on emp sub category(DFF 2). if we select 1 from DFF1 and A from DFF2 then it should show 1A, and if we select 2 from DFF1 and B from DFF2 then it should show 2B)
