Dropdown and text field linking

Hi,

You can put a show when condition that when dropdownValue="Other" then a text field will show. In the text field you can map the rule input to save data where name is getting stored. Make sure to stored both the dropdownValue and text field value in different variable. 

a!localVariables(
  local!list: { "Ramesh", "Somesh", "Other" },
  local!selectValue,
  local!otherValue,
  {
    a!dropdownField(
      label: "Name",
      choiceLabels: local!list,
      choiceValues: local!list,
      value: local!selectValue,
      saveInto: local!selectValue,
      placeholder: "Select a Value"
    ),
    a!textField(
      label: "other",
      showWhen: local!selectValue = "Other",
      value: local!otherValue,
      saveInto: {
        local!otherValue,
        if(
          contains(
            touniformstring(local!list),
            tostring(local!otherValue)
          ),
          "",
          a!save(
            local!list,
            append(local!list, local!otherValue)
          )
        )
      }
    )
  }
)

Hi, You can use below code 

a!localVariables(
          local!Choicevalue: {1,2,3},
          local!values,
          local!OtherName,
a!sectionLayout(
      contents: {
           a!dropdownField(
                label: "Name",
               placeholder: "select a name",
               choiceLabels: ri!DropDownValues,
               choiceValues: local!Choicevalue,
               value: local!values,
               saveInto: local!values
  ),
a!textField(
         label: "Name",
         value: local!OtherName,
         saveInto: local!OtherName,
         showWhen: if(tointeger(local!values)=3,true(),false())
    )
  }
 )

)

Here, I have made one rule input for dropdown field and use a local!values for saving the dropdown values, 

And in text field you can use showwhen when other option is selected then text field show other it can't show.
