Is anyone ever made a dynamic drop down list depending to another ?

I want to design a drop down list depending to another in PDMLink 10.2

Sample :

If user chooses into the drop down list "A", value "Val1_A", then my down list "B", displayed values "Val1_B" and "Val2_B"

If user chooses into the drop down list "A", value "Val2_A", then my down list "B", displayed values "Val2_B" and "Val2_C"

Thx,

Romain
