    You can simply do that by using the append() function. If it doesn't work, please attach your code for better understanding of what you're doing wrong.

      Hi Harshit,

      thanks for your reply, getting this error

      code:

      a!localVariables(
      local!values:rule!MSAJ_getAllBrands(),
      local!saveValue,
      {
      a!sectionLayout(
      contents: {
      a!dropdownField(
      label: "Brand",
      labelPosition: "ABOVE",
      placeholder: "--- Select a Value ---",
      choiceLabels:append(local!values),
      choiceValues: append(local!values),
      value:local!saveValue,
      saveInto: local!saveValue,
      searchDisplay: "AUTO",
      validations: {}
      )
      }
      )
      })

      choices values can not be null  , append function takes array and values as parameter and you are passing only array into this but this is not the error which is showing on screen, your local!values variable has a null value which should not be.

      and I think you do not have any use of append function , you can just simply pass the variable and it will be fine  until unless you have use for that .

      and try replacing line 2 with below piece of code

      reject(a!isNullOrEmpty,local!values:rule!MSAJ_getAllBrands()) // this will simply reject null values in an array

      Hi @manik0004,

      You need to create expression rule to get the desired values list without using rule inputs first. Then, just call that expression rule in the choice values and labels. It'll work as you expected.
