Hi,

a!dropdownField(
placeholder: "Select-Country",
choiceLabels: index(local!Countries,"country",null()),
choiceValues: index(local!Countries,"countryId",null()),
value: fv!item.country,
saveInto: {fv!item.country,a!save(fv!item.state,null())}
),
a!dropdownField(
placeholder: "Select-state",
choiceLabels: if(a!isNullOrEmpty(fv!item.country),local!states.state,index(local!states[wherecontains(tointeger(fv!item.country),local!states.countryId)],"state",null())),
choiceValues: if(a!isNullOrEmpty(fv!item.country),local!states.stateId,index(local!states[wherecontains(tointeger(fv!item.country),local!states.countryId)],"stateId",null())),
value: fv!item.state,
saveInto: {fv!item.state,
}
),

Local variables:-

local!Countries:{
a!map(countryId:1,country:"India"),
a!map(countryId:2,country:"USA")
},
local!states:{
a!map(stateId:1,countryId:1,state:"Andhra Pradesh"),
a!map(stateId:2,countryId:1,state:"Telangana"),
a!map(stateId:3,countryId:2,state:"Canada")
},

Go through the code and follow logic for your code.
Based on selected country, state choice values will be changed.

Here wherecontains used to get the index of the match country and from local!states it will get the values based on the index.

hello, thank to all for the replies.

Tejakunchala, you are correct, I´m trying to perform cascading dropdown like from first drop down based on selected value, I want to get the choice values in the second drop down ( autopopulate in the second dropdown).

This is a start form, so it´s is writng to a record on the PM.

can you pls guide me on the code you are suggesting me.

thanks a lot.

Hi,
Did got the question.
From my assumption,
You are trying to perform cascading dropdown like from first drop down based on selected value you want to get the choice values in the second drop down
If that is the case then use wherecontains in choice values and choicelables to get the value.
Or
If you are trying to write into database provide writerecord in submit button or use process model for writing the data to database.
Provide detailed view if these are not the cases.

Not sure but I think you want write a record using a array.

I assume that you are trying to update the record in the database, using the saveInto parameter in the dropdown.

This will only update the record locally, but will not save it to the database. If you want to update the record in the database, you will have to use either the smart service Writerecords in a PMO or the a!writeRecords function in your interface

The code you shared does not include anything that would save data to the database.
