What's the problem this feature will solve?
Only SliderInt and SliderFloat inputs are currently available, and neither of these are documented in the user-facing documentation.

Describe the solution you'd like
Support for solara select and improved documentation.

Additional context
Some discussion on #1772

I have the Solara select mapping implemented and working in a local fork; I will be glad to add some suggested changes to the documentation and open a pull request with these changes.
