A while back, I used this great blog post
and related discussions to create and use an image selector as a custom field for the Blog module. I've also seen the same approach to create a document picker.
I have a need to create a simple multiple choice dropdown list as a custom field for my News module. However, the choices won't be static as they are to be created dynamically.
I've done this in a custom module before as well. Just not sure how you'd do it inside one of the pre-built modules like News.
Can you provide any code samples or point me in a direction so that I might achieve this?
