Dynamic action - show/hide region based on LOV which returns ID

Question

Hi folks,
this should be simple, so someone who works with dynamic actions.
I have a LOV which is based on below query:
select OBJECT_ID, KOD
  from x_data x;
retuns:
   ID          KOD
    492961 BMW
    492964 VOLVO
    492960 MERCEDES
    492963 VOLKSWAGEN
    492959 SKODAItem :P200_KOD is based on LOV which displays KOD and returns ID.
On my page I have also 1 region called TEST_REGION.
I would like to set up a dynamic action shich will SHOW/HIDE a TEST_REGION based on selected value in item :P200_KOD (LOV). Region should be showed if displayed (KOD) value of selected ID starts with 'V%'
By other words, if below query returns any record, then SHOW, else HIDE:
   select *
    from x_data x
  where x.kod like 'V%'
     and x.object_id = :P200_KOD;How should I define a triggering condition for dynamic action, for item :P200_KOD?
Thanks,
Tomas

Hi,
One way:
Create advanced dynamic action.
Name : Hide region
Event : Change
Selection Type : Item(s)
Items(s) : P200_KOD
Condition : JavaScript Expression
Value :
$(this.triggeringElement).children("option:selected").html().substring(0,1) !== "V"Action : Hide
Fire On Page Load : True
Hide all page items on the same line : No
False Action : Show
Fire On Page Load : True
Show all page items on the same line : No
Selection Type : Region
Region : TEST_REGION
