i cannot hide item options based on the item, can i? that would require custom JS scripting?

I’m pretty sure this is built in but needs some configuration. You need to create a new transaction item option and then if you go to configuration make sure this field is checked: SHOW ONLY ITEMS LISTED IN: ITEM OPTIONS AND CUSTOM TRANSACTION COLUMN FIELDS Then in the tabs below there’s a table called Item options and custom transaction column fields. Make sure the id of your option is in there

Yes, that is correct. By default we show all options unless you create a whitelist
