Convert [group: xxx] to a text value with togroup

Question

I need help. I have a dropdownField where I select three options but they come to me like [group: 67] [group: 68] [group: 69] but these values ​​(office 2300, office 2450, office 2800) I have them in a constant. I'm trying the example below but I can not get it in the dropdown I get the values ​​I want (office 2300, office 2450, office 2800) and not the ones that come out ([group: 67] [group: 68] [group: 69]) 
 
 a!dropdownField( label: "OFFICE", placeholderLabel: "Selection", choicelabels: { cons!CP_ typeOffice }, choicevalues: { cons!CP_typeOffice }, value: local!filter.type, /*value: togroup(local!filter.type),"description",*/ saveInto: local!filter.type ), 
 
 thanks

Hi, 
 You need Group Name by GroupId, try below code, 
 
 a!dropdownField(
 label: "OFFICE",
 placeholderLabel: "Selection",
 choicelabels: {
 apply(
 group(_,"groupName"),
 tointeger(cons!CP_typeOffice)
 )
 
 },
 choicevalues: {
 tointeger(cons!CP_typeOffice)
 },
 value: local!filter.type,
 saveInto: local!filter.type
), 
 
 Thanks 
 Vinay

Just FYI, unless you're using a very old version of Appian (ie pre ~17.2), you should definitely use a!forEach() and not apply(), both for code clarity as well as to ensure you're more future-proof. 
 a!dropdownField(
 label: "OFFICE",
 placeholderLabel: "Selection",
 choicelabels: {
 a!forEach(
 cons!CP_typeOffice,
 group(fv!item, "groupName") /* you can also wrap fv!item in tointeger() if you're worried but it shouldn't be needed */
 ) 
 },
 choicevalues: {
 tointeger(cons!CP_typeOffice)
 },
 value: local!filter.type,
 saveInto: local!filter.type
)
