Boolean dropdown instead of tickbox

Is there a built in method to change a boolean value in a fieldgroup to a dropdown picker instead of a tickbox?

Hi,

There is no such built-in method. In order to use dropdown, you can either use an enum instead of boolean or define a custom component for a boolean field in a screen. In case of using LookupField, you can define options list or options map to represent boolean values.
