Hi folks,
New to Appian!
I need to create an interface which will allow a user to select/unselect the countries based on regions.
Description:
1. An Interface is having 2 dropdown lists first Region List and second is Countries list. (created)
2. All countries belongs to selected region must be selected automatically whenever an user selects a region.
3. An user can unselect one or more country(s) from the countries list if he wants.
Looking for a detailed suggestion or solution to implement this functionality.
Thank you in advance!
Regards,
Shubham Kumar

This code snippet should help
a!localVariables( local!regions: { { id: 1, name: "Region 1", }, { id: 2, name: "Region 2", }, { id: 3, name: "Region 3", } }, local!countries: { { id: 1, name: "Country 1", regionId: 1 }, { id: 2, name: "Country 2", regionId: 1 }, { id: 3, name: "Country 3", regionId: 1 }, { id: 4, name: "Country 4", regionId: 2 }, { id: 5, name: "Country 5", regionId: 2 }, { id: 6, name: "Country 6", regionId: 2 } }, local!selectedRegion, local!selectedCountries, { a!multipleDropdownField( label: "Region", choiceLabels: local!regions.name, choiceValues: local!regions.id, value: local!selectedRegion, saveInto: { local!selectedRegion, a!save( local!selectedCountries, a!flatten( index( local!countries.id, wherecontains( tointeger(local!selectedRegion), tointeger(local!countries.regionId) ), {} ) ) ) }, placeholder: "---Country---" ), a!multipleDropdownField( label: "Country", choiceLabels: a!flatten( index( local!countries.name, wherecontains( tointeger(local!selectedRegion), tointeger(local!countries.regionId) ), {} ) ), choiceValues: a!flatten( index( local!countries.id, wherecontains( tointeger(local!selectedRegion), tointeger(local!countries.regionId) ), {} ) ), value: local!selectedCountries, saveInto: local!selectedCountries, placeholder: "---Country---" ) } )

User can select multiple regions at a time, and countries belongs to regions must be auto selected in countries dropdwon list
