Hi all!
Is there a way in ng-formly to handle dynamic options in select type?
(similar issue from angular-formly)

Certainly. This plunker demonstrates a customized select that's intended to work with objects (group capability isn't fleshed out), restore selection, and handle default values:

If all you're after is something similar to the issue you linked from angular-formly, the built in type will handle that as well. This is the above example using the select field type that is packaged with ng-formly:

Thanks for these examples. Is there a way to use arrow function instead of onInit: function() {...} and still get the access to to.options param?

Not that I'm aware of.

This is the answer for my last question I believe :)
