Hi,

Is there a decent guide for how to create a setup of two select boxes, where the secondary one populates its options based on the selection of the primary one?

I’d like to use Stimulus and Turbo but can’t find an up to date modern solution that uses both in order to take inspiration from.

Any suggestions? Or a set of steps to achieve this?
