My question is 2 parts:
1st, is there a simple method to hide all items, initially in JEI?
2nd, How would I go about then showing those hidden items based on data received from the server?
I'm creating arrays of items that I want to un-hide when the server sends data to the client. I've found examples to accomplish this for previous versions, but a lot seems to have changed for 1.19+, and I'm not familiar enough with javascript to translate them.
