I don't know as much about the underlying issue as the sibling, but I've also found that LiveView and AlpineJS interact in complex and unexpected ways in the case of components. The only sane way I found to integrate them was to make an Alpine-based component which is solely responsible for rendering itself, and then communicate updates back and forth with the LiveView process via custom events. That works but it's fairly heavyweight.
I would like to be able to use Alpine in precisely the cases where the JS commands aren't enough. This case was one of those accursed custom form controls that designers love to come up with (a dropdown with checkboxes and a search filter).
Ha, right. I was in that same position. Unless you're working with a fixed, non-search, massive dataset, I found the performance is just fine doing it in pure Liveview over the socket, but I don't know your situation.
Yeah, indeed, doing it in pure LiveView is a realistic option, but it does degrade the user experience for e.g. someone on a crappy 3G mobile connection.
