Hello, I'm still learning and cannot figure out how to do this in your repeater code:

  • Have image chosen from the wp media library
  • have wp embedd dialog for youtube, Vimeo and similar content

Thank you if you have time 👌the code is very useful to me already, but these 2 solutions would be excellent.

I want select menu instead of input box, so I modified the above code, but it is not working. Whenever I click on update button, it adds a new repeater field and previously selected values are not displayed. Can anyone help?

Hi @vinay123456 , Yes this was copied from stackovflow I guess. I used to use this code in many projects frequently. So I created this gist to find this code quickly. Obviously I was making self logic on top of this code.

Thanks for sharing this code block.
