In this admin form to create a page with some fields, the user will choose the path and the list of PPD property of that path will display on the select list. After that the admin will sync and save the data.
When they choose "View properties" to edit the page, I want the select list will be select the previous value.
Thank you for your help,
Try writing the logic in a backend service which reads and returns child nodes under the path specified and from your JS file, ajax a servlet which brings all the required content through the service.
Hope this helps!
If you know the path, make a request directly from browser with .json without servlet/service. I am assuming this is only author specific case.
