How to add a hidden 'comment' field to the formData?

What is your question?

We have a use case as follows:

1. We have different product variants that use different JSON Rule Schema files to generate their Configuration Files (formData)

2. When a user loads a Configuration File in our editor from device type A, the editor should automatically load Rule Schema A

In order to achieve the above, we are currently looking for certain fields in the loaded formData - but that is not very scalable or robust. Instead, we'd prefer to add a 'variant identification field' in the formData/Schema. This field should not be displayed in the front-end (regardless of UIschema) and is purely for internal purposes - like a comment field.

Is this possible to achieve in rjsf?

Yeah I wanted to stuff a form version number in mine. I guess I'll just have to add it when saving, and remove it when loading.

I wanted a "ui:hidden":true option

[adjenks]

I figured it out. This is my solution for hiding fields:

const schema1_0: RJSFSchema = {
	title: 'Test form',
	type: 'object',
	properties: {
		version: {
			title: ' ',
			type: 'string',
			default: "1.0"
		},
	},
}

const uiSchema: UiSchema = {
	"version": {
		"ui:inputType": 'hidden'
	}
}

It seems like you have to have a title of ' ' for it to work. Empty string will default to the field name.

Addendum: I am noticing now that some styling libraries will still display an empty box with this configuration, which is sort of ugly. It's still pretty close though.

"ui:widget": "hidden" works much better, it doesn't leave an empty box.
