Thank you Gaurav for you help.
Glenda here is actually what I want.
Our organization has multiple sectors and each sector has multiple locations. There are thousands of locations. Right now I have two LAH that populate two drop down option lists, viz., Sectors and Locations.
When a user selects a sector, I want to filter down the Locations options list to show only those locations that belong to the selected sector.
I do not know where to apply this filtering logic.
Regards,
Arij
