Build a callback that runs on page reloading

Hello, I’d like to build an output only callback that fills some data to dropdown menus upon page reloading. However, it seems I have to provide Input to any callback. So how can I achieve this behavior?

You can just add a dummy object on the page, e.g. a Div component, that you use as an input.
