Dropdown Field Value Selection impact on another Dropdown Field

HI maheshg821223 ,

There are many different ways to achieve the expected result. I hope this snippet provides you with some ideas.

a!localVariables(
  local!values: { true(), false() },
  local!labels: { "Yes", "No" },
  local!dropd1: null(),
  local!dropd2: null(),
  a!columnsLayout(
    columns: {
      a!columnLayout(
        contents: a!dropdownField(
          label: "Dropdown 1",
          choiceLabels: local!labels,
          choiceValues: local!values,
          placeholder: "Select a value",
          value: local!dropd1,
          saveInto: {
            local!dropd1,
            a!save(
              local!dropd2,
              a!match(
                value: local!dropd1,
                whenTrue: fv!value,
                then: false(),
                default: null()
              )
            )
          }
        )
      ),
      a!columnLayout(
        contents: a!dropdownField(
          disabled: and(local!dropd1, not(local!dropd2)),
          label: "Dropdown 2",
          choiceLabels: local!labels,
          choiceValues: local!values,
          placeholder: "Select a value",
          value: local!dropd2,
          saveInto: { local!dropd2 }
        )
      )
    }
  )
)

An example

a!localVariables(
  local!drop1: { "Yes", "No" },
  local!drop2: { "Yes", "No" },
  local!save,
  local!save2,
  {
    a!dropdownField(
      placeholder: "please select",
      choiceLabels: local!drop1,
      choiceValues: local!drop1,
      value: local!save,
      saveInto: local!save
    ),
    a!dropdownField(
      placeholder: "please select",
      choiceLabels: local!drop2,
      choiceValues: local!drop2,
      value: if(local!save = "yes", "No", ""),
      saveInto: a!save(local!save2, save!value),
      disabled: if(local!save = "yes", true, false)
    )
  }
)

Hi maheshg821223 ,

a!localVariables(
  local!choice: { "Yes", "No" },
  local!value1,
  local!value2: null(),
  a!columnsLayout(
    columns: {
      a!columnLayout(
        contents: a!dropdownField(
          label: "Dropdown 1",
          choiceLabels: local!choice,
          choiceValues: local!choice,
          placeholder: "Select a value",
          value: local!value1,
          saveInto: { local!value1,  }
        )
      ),
      a!columnLayout(
        contents: a!dropdownField(
          label: "Dropdown 2",
          choiceLabels: local!choice,
          choiceValues: local!choice,
          placeholder: "Select a value",
          value: if(
            local!value1 = "Yes",
            a!defaultValue(value: local!value2, default: "No"),
            local!value2
          ),
          saveInto: { local!value2 },
          disabled: local!value1 = "Yes"
        )
      )
    }
  )
)
