Document Drop down

I think you can have something like this, Document names as a choice labels and document numbers as choice value. This way you can give it a try.

I have tried this code and the values dont poplate on the dropdown:

load(
local!doc: null,
local!doc: tointeger(
a!forEach(
items: cons!FOLDER__ID,
expression: folder(
fv!item,
"documentChildren"
)
)
),
with(
a!dropdownField(
label: "Document",
choiceLabels: {
a!forEach(
items: local!doc,
expression: document(
documentId: fv!item,
property: "name"
)
)
},
choiceValues: {
a!forEach(
items: local!doc,
expression: document(
documentId: fv!item,
property: "name"
)
)
},
placeholderLabel: "Select a document...",
value: local!doc,
saveInto: local!doc
)
)
)
