How do I populate a field(Drop down) in Appian using Fitnesse which is present under a section but has no label.

Here is the piece of code for reference:-

a!sectionLayout(
      label: "Select Relationship Type",
      contents: {
        a!columnsLayout(
          columns: {
            a!columnLayout(
              contents: a!dropdownField(
                label: "",
                choiceLabels: {
                  local!relationTypeLabels
                },
                choiceValues: {
                  local!relationshipTypeCodes
                },
                placeholderLabel: " --- Select a Value --- ",
                value: ri!entityType,
                saveInto:{
                  ri!entityType,
                  if(
                    rule!APN_isBlank(ri!entityType),
                    {
                      a!save(ri!primaryEntityData,{}),
                      a!save(ri!secondaryEntityData,{}),
                      a!save(ri!isAltSCSelected,null),
                      a!save(ri!isSelected,null),
                    },
                    {}
                  )
                }
              )
            ),
            a!columnLayout(
              rule!SCE_dummyTextFieldForExtraSpace()
            )
          }
        )
      }
