Comment:

 @nikeo I think it is natural to fetch the settings for the controls in a
 given section upon the expansion of the section, and not before. I mean,
 if we did this for nav menu items, then we wouldn't know that the settings
 for nav menu items would need to be fetched. We'd only know to fetch them
 once the section is expanded. As such, I think there should be a spinner
 that shows inside of a section while this request is being made, and then
 when it completes the nav menu item controls would get populated into it.
 If you wanted to do this the other way around, where you programmatically
 know up-front that you need to populate a section with controls, then you
 could do that Ajax request and create all of the settings and controls (as
 in the `populateFooSectionControls` example above), and then after
 completed, expand the section. In either case, however, you'll need a
 spinner to show that some Ajax request is being done.

 I'm thinking this can be closed as `maybelater`.
