Prerequisites

• [X] I have searched the existing issues
• [X] I understand that providing a SSCCE example is tremendously useful to the maintainers.
• [X] I have read the documentation
• [X] Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

material-ui

Version

5.5.0

Current Behavior

The accept option is not applied to the input using any theme except the default theme. Other options are applicable.

Expected Behavior

When passing the accept option it should add the accept=".fileType" to the input element.

Steps To Reproduce

This can be found on the playground link and has proven to be broken except on the default theme. https://rjsf-team.github.io/react-jsonschema-form/

Environment

- OS: macOS
- Node: v16.19.1
- npm: 8.19.3

Is this for files?

[samialitop3]

Yes, this is for files that are defined in the schema like this file_element: { type: 'string', format: 'data-url', }

and in the uiSchema when defining the ui:options to be { accept: '.pdf }`}, it works only with the default theme, all other themes don't work.

@samialitop3 AH, yeah, this is an issue for many of the themes. I think that the material-ui themes might work given how they are implemented.

@heath-freenome The material-ui theme is not working as well, you can check it on the playground link

Looks like 'multiple' also doesn't work on MUI v5. Not sure whether to create a new error or include it in this one.

Keep it in this one

@heath-freenome Any updates on this?

@samialitop3 Given we have a few, very busy volunteers maintaining the project, we rely largely on contributions from people who are willing to provide fixes/features. Are you able to help on this?
