Hi there is a WD component called WDR_TEST_EVENTS. All the UI elements are explained very clearly with examples. You can go through this component and and find information relevant to your need.

Thanks,

Hi Supriyo,

You can use the onSelect event of each predecessor dropdown to populate the value list of its successor.

1. Create an onSelect event for the ZONE dropdown in which you populate the value list of WARD. 
2. Create an onSelect event for the WARD dropdown in which you populate the value list of COLONY.

You can programmatically set the value list of a dropdown by using method set_attribute_value_set of the interface if_wd_context_node_info.
