hmmm, my implementation of a thing similar to aboves SearchTextFieldDropdown: if I put

Column { for (i in 1..100) { Text("item $i") }

inside a `@Composable DropdownMenu()`'s

dropdownContent

the dropdown "disapears" if height is larger than the window height (and I cannot put it into an explicit LazyColumn as

dropdownContent

Clause is already a

ColumnScope

Is this a bug, or am I doing something wrong? (or is DrowdownMenu not meant to show things with height > Window.height?)

The current drop-down implementation is limited to the window bounds. Right now you'd need to rollout your own implementation, probably based on JWindow and ComposePanel

yeah ... just also realized, that if the DropDown is visible and I resize the window a few times (making it smaller than the dropdown, bigger, small, bigger - while continuously holding the mouse key, you start first seeing white-non repainted areas and then the redrawing completely ... hmm, let's say "gives up"

but this doesn't happen to be the case "all" the times ...

also I wonder (completely different topic) why I connot make the Dropdown visible again (with its former contents) on clicking on trailingIcon `TextField`s

trailingIcon = {
                    IconButton(
                        onClick = { println("trailing search icon click") ; searchPopupVisibleState.value = true }
                    ) {
                        Icon(Icons.TwoTone.Search, contentDescription = "Top Search")
                    }
                },

onClick is not called at all, on pressing the trailingIcon (same with leadingIcon)
