@Marvin Is there any way to get a dropdown menu for a flow param?

It seems that Prefect does not natively support creating a dropdown menu for flow parameters directly within the UI. However, you can define flow parameters using Python functions, including type hints and Pydantic models, which Prefect will understand and enforce during flow execution. For a more interactive interface, you might need to build a custom front-end or use a third-party tool to interface with Prefect's API, allowing users to select parameters from a dropdown and then pass those to your flow. For more details on defining flow parameters, you can refer to the Prefect documentation on writing flows.
