Ok, this is the solution
-
type: 'TYPO3.Form:SingleSelectDropdown'
identifier: paket
label: 'Paket'
properties:
options: ['First', 'Second', 'Third']
but how can I add values. Currently they are 0,1,2
I have tried
options: ['First', 'Second', 'Third']
values: ['First', 'Second', 'Third']
but it does not work :-(
