docs: Simple between datetime example

[Dennis Haney (davhdavh)]

🙋 Documentation Request

It would be really nice if there was a simple example in the date/time picker section with the extremely common case of picking a range.
I.e. 2 inter-dependent fields From and To.

Not really an issue... converted to a discussion

It'd be really good to be able to select a range from a single date picker.
