Has anyone made compose implementation of

AutoCompleteTextView

? I know I can just use the existing one but having it implemented in Compose would make it more flexible I feel.

All you need is a dropdown, a lazycolumn and a text field. Compose them into what you need.

Yeah I was planning to. But why do I need dropdown? I can simply make a Column and show the suggestions list conditionally right?

Just so you get the popup. Although that's somewhat opinionated.
