Hi  
I have initially some static JSON data & uischema. Now few fields are dynamic so how can I add uischema to dynamic controllers

Basically is there any way to generate uischema dynamically

Hi @ritu,

you can invoke the built-in UI Schema generator like this:

```auto
import { Generate } from '@jsonforms/core';
const uischema = Generate.uiSchema(schema);

```

Of course you could also generate it yourself, the [generator code](https://github.com/eclipsesource/jsonforms/blob/075bbc448cfb2bb209e86d6b1ea6460df23a9f64/packages/core/src/generators/uischema.ts#L115-L202) is just about 100 sparse LOC.

Thanks a lot !! & also can we make these fields optional

Cause am doing `Generate.jsonSchema(tempJson, {additionalProperties: {required: false}})`

which has no effect

You can just iterate over the generated schema and remove all `required` fields.

In case you would like to use the generation options instead I think the following should work (untested)

```auto
Generate.jsonSchema(json, { required: () => [] } );

```
