Been playing around with it for awhile, but with no luck. Here’s what Im trying to do:
1. I have a Repeater field named ‘slides’
2. Within that repeater field, I gave a Group sub field named ‘templates’
3. Within that sub field, I have a Group sub field named ‘default’
4. Lastly, within the default sub field, I have a Radio field named ‘image_size’
What I’m trying to is dynamically add the available WP image sizes in that field. I need help on customizing the default sub field options.
