Please see rjsf-team/react-jsonschema-form#1222 and take a look at https://github.com/cybertec-postgresql/rjsf-material-ui for a material-ui widget theming of RJSF that hooks into their new theming approach.
TODO: push to NPM
npm i material-ui-react-jsonschema-form
This package exports a Form object that renders using material-ui by default.
Unlike other similar packages, this is, a customization of react-jsonschema-form rather than a fork or reimplementation of it and keeping up to date with that project should be quite a bit simpler.
Use of this package should be roughly the same as react-jsonschema-form.
Visit the playground at https://cwhatley.github.io/material-ui-react-jsonschema-form/
You can launch a playground that has been ported to material-ui via npm start.
