Prefilled, readonly text field for `const` string types

[mmkal]

Prerequisites

• [x] I'm providing a shared playground link demonstrating the issue.

Description

[Description of the bug or feature]

Steps to Reproduce

1. Have a schema using { "type": "string", "const": "something" }

Expected behavior

The input should have the const value already filled in, and have readonly=true

Actual behavior

The input is just a regular textbox, and the user has to type the exact value of const manually (without even a hint of what the value should be)

Version

3.2.0

I'd be happy to open a PR to improve this if someone could point me in roughly the right direction.

Same issue, I wonder if we can create a custom widget for it

@mmkal Are you still willing to fix this? Some refactoring that was done in version 5 should make fixing this fairly simple. There is a new method in @rjsf/utils called getInputProps() that would be the place to add the fix. The code can be found in the rjsf-v5 branch until it is merged into the master branch when the v5 beta is published

@heath-freenome sorry I missed this message. I'm not using rjsf at the moment any more, so probably won't do this any time soon.
