Hi gopalk0002 You can achieve this by saving the values to be shown in the second drop-down on the selection of 1st drop-down and show the second one only after the first is selected. Make sure to do a null condition if the option is changed in the first one. Something like this. load(
 local!dropdown1: {1,2,3},
 local!value1,
 local!value2,
 local!dropdown2,
 {
 a!dropdownField(
 label: "Dropdown 1",
 placeholderLabel: "Please select",
 choiceLabels: local!dropdown1,
 choiceValues: local!dropdown1,
 value: local!value1,
 saveInto: {
 local!value1,
 a!save(local!value2,NULL),
 if(local!value1=local!dropdown1[1],a!save(local!dropdown2,{4,5,6}),a!save(local!dropdown2,{7,8,9}))
 }
 ),
 a!dropdownField(
 showWhen: not(rule!APN_isBlank(local!value1)),
 label: "Dropdown 2",
 placeholderLabel: "Please select",
 choiceLabels: local!dropdown2,
 choiceValues: local!dropdown2,
 value: local!value2,
 saveInto: local!value2
 )
})
