Here is the code https://github.com/AtomicSmash/ACF-page-builder. I’ve bundled it into a plugin for easy testing.
So the code is pretty simple and probably a bit buggy (it’s about 12 lines of jQuery). Like I said before, I don’t particularly want to support this as it’s only a prototype, so please fork away.
Instruction on setup are in the repo readme.
When you see how little code it takes to modify the ACF Flex content field to do this, I think it speaks testament to what a great job @elliot Condon has done with ACF and how ‘flexible’ it truly is. *MEGA PROPS*
