In this example we show how to make the values in one select depend on the value selected in another select.

To begin we start with a default value for the make select: Audi. We render the model select for this make. We then have the make select trigger a GET to /models to retrieve the models options and target the models select.

Here is the code:
::page::

When a request is made to the /models end point, we return the models for that make:
::models::

And they become available in the model select.
