Imagine this scenario, we have an EC2 instance with multiple disk, and/or security group rules. Current solutions might be: JSON objects (with JSON schema validation) An input like "how mane disk", and then hide/unhide pre-created inputs Both are today not perfect for all use-case, use of JSON might no be trivial for all population, and use of hide/un-hide inputs as a latency because of the jq-calculation. Would it be possible to imagine a modal that can pop-pup to add/remove item from a list
