 * I’ve been struggling for hours to find some guidance as to how to make the Choices
   Callback work, I don’t know how to populate the defined field. I found how to
   do the function at [https://www.snip2code.com/Snippet/1669213/Example-Callback-function-for-Ultimate-M/](https://www.snip2code.com/Snippet/1669213/Example-Callback-function-for-Ultimate-M/),
   but when I add getCities() to the Choices Callback field in the editor, it says
   I must still add edit choices, so I can’t continue.
 * What are the steps to populate the field, what should be in the
    Choices Callback
   and Edit Choices fields in the editor when my function’s name is getCities() 
   in functions.php?

 * I found a solution by trying 1mil things.
 * The WP Backend Field must look like this:
 * The `Edit Choices` field can’t be empty (this is definitely a bug), so you have
   to put something in there like an `*`.
 * Then, in the `Choices Callback` field, you must add your PHP function name, with
   no brackets. Ie, if your PHP function in functions.php is `function getCities(){...}`,
   the field must contain only `getCities`.

 * Thanks for putting the solution to your problem. That is very helpful. I am just
   starting to work with callback choices and you just saved me major future headaches.
   Thanks!
