Save the values and display it into a rule input by a!foreach loop for version 21.1

Question

Hi All, 
 
 How to save a values and display that values into rule input by a!foreach loop? 
 for example : in a!foreach loop there is a condition that text1 is having a datatype "string" value. I want to dynamically populate text fields in a form layout interface. How to save the user response? 
 a!forEach( local!data, if(fv!item.text1= "String",{ a!textField( label: fv!item.text1, labelPosition: "ABOVE", saveInto: {}, refreshAfter: "UNFOCUS", ) 
 }) 
 ) 
 
 Please guide me how to achieve it for version 21.1.

Hi Yash, If you are using a!foreach then to save these values , you would need to create your rule input as type of array, then using fv!index you can save the values. Please see below sample example, 
 a!localVariables(
local!data:{"value1","value2"},
 a!forEach(
 items: local!data,
 expression: {
 a!textField(
 label: "text field" & fv!index,
 value: fv!item,
 saveInto: {
 fv!item,
 a!save(ri!data[fv!index],save!value)
 }
 )
 }
 )

) 
 
 my rule input here is array type. I hope it helps.
