Generic dialog based on html form

[fcollonval]

In the following discussion
jupyterlab/jupyterlab-git#345 (comment)
or when I worked on the input dialogs #6326, it appears extensions developers could benefit from a generic form widget similar to the dialog.
That would open the door to Webbrowser validation for example.
Is there any example of such widget? Would it be a nice addition to the base code? Is there other source of inspiration than the Dialog widget?

The 💰 would be react-jsonschema-form. Basically, write (only slightly opinionated) schema, get form.

By default, it carries the bootstrap baggage, and the blueprint theme is hard to reason about because its listed repo isn't public (or something). But, as the rjsf docs rightly suggest, it's possible to do a lot with the relatively concise dom bootstrap does create.

Here's an example of using it in a widget:

(binder) (repo)

Having it in core, integrated with a ui-components theme would make a ton of sense.
