Considering Observable Framework, but before I dive in: can selections presented to a user update, based on other selections they make, even in a statically generated OF app?

Here's an issue I run into with other statically generated dashboards: suppose that I have data that has two columns that can be used to categorize it: channel (e.g. "A", "B", "C") and flavor ("spicy", "mild", "sweet").

We can give the user a dropdown for channel and flavor, letting them choose amongst the available choices. We filter the data itself first by channel, and then by flavor, because not all flavors are available for each channel.

I want the selections available for flavor to update based on the choice made by the user for channel. With something simple like Quarto + Altair, this is not possible.

Is it possible with Observable Framework?

If you mean can you update data based on user selections in page, then yes, a Framework application is reactive:

There are built-in tools and inputs for giving user controls that will cause graphs and page elements to re-render based on those choices.

The specific behaviour you are describing (faceted filtering) is also possible to implement, but there's no built-in tooling for that.

So nothing stopping you from doing it, but you'd be doing it.
