Creator JS SDK - How to use any "array" field??

Hi team,

I've tried every single way to addRecord where I want to parse an array, just ANY array.

I don't know why there is no single field that would allow me to use this dynamically. I tried multi select, which when I fetch the record, it returns an array, while when I try to add/update, it's seems impossible to do so.

After long discussion with support, I wasn't able to get an example for SubForm items add/update through JS SDK. Can someone with experience how to manipulate any array structure through JS SDK.

I hereby suggest the team, the JS SDK needs just a LITTLE work, of few more methods and more necessarily DOCUMENTATION, and it will become a very powerful SDK to use, therefore I guarantee Creator will get attention to many other JS developers. For example for us, so many things that weren't written in the documentation became obstacles and total game-changers, so we had to find workarounds for most of the things. This could be much pleasant experience if few KEY features weren't missing, or at least the documentation was detailed enough to tell us upfront for the limitations.
