How can we split a comma-separated string fetched from the database (e.g : "Java,Python,SAIL,Dart") into a list and display it as a dropdown in an Appian interface?

Will use the split function to divide string to list

a!localVariables(

local!data: "Java,Python,Sail,Dart",

split(local!data, ",")

)

Output

Save this rule and call this interface:

Final Code

a!localVariables(

local!data: "Java,Python,Sail,Dart",

local!list: split(local!data, ","),

{

a!dropdownField(

choiceLabels: { local!list },

choiceValues: { 1, 2, 3, 4 },

label: "Dropdown",

labelPosition: "ABOVE",

placeholder: "--- Select a Value ---",

saveInto: {},

searchDisplay: "AUTO",

validations: {}

)

}

)

Output
