I have the phenomenon with a customer in Modx that some inputs on the repeaters are loaded forever, actually always without success.
Admittedly, we have several hundred resources that often also use Contentblocks elements. Is there anything I can do to optimize this process, or is it a problem with too many resources?
Are you seeing any errors in the MODX error log or the browser console when this happens?
Also, how are you populating the dropdowns that are not loading?
Could you provide a screenshot of the input properties?
