Hi 
I am working on an input in a form with a custom autocomplete dropdown. I would like to realize it without a lot (or any) JS. I managed to create a working component, using phx-keydown events on the input. When keys like arrows, enter etc are pressed the autocomplete element is updated or the selected suggestion applied.
I am quite confused why it says in the docs that phx-keydown is not supported on inputs. The alternatives, installing a key listener on the window etc won’t work because I need to know in which element the keypresses originated. The other suggestion, to use phx-change also can’t support a UI like this, because I will get events when the content of the input changes but not when the user presses some arrow keys.
Does anyone know what “not supported” means here and why?
