Is there any standard implementation in Jetpack Compose for visual component like Spinner/Wheel Picker or Dropdown Button?

You can use a Button with a DropdownMenu.
Something like:
var expanded by remember { mutableStateOf(false) } val suggestions = listOf("Item1", "Item2", "Item3") Button(onClick = { expanded = !expanded }){ Text ("DropDown") Icon( imageVector = Icons.Filled.ArrowDropDown, contentDescription = null, ) } DropdownMenu( expanded = expanded, onDismissRequest = { expanded = false }, ) { suggestions.forEach { label -> DropdownMenuItem(onClick = { expanded = false //do something ... }) { Text(text = label) } } }

I recommend wrapping the
DropdownMenu in a Column or a BoxYes, as @kc.dev commented, the button and the dropdownmenu better be in a box like the following. Otherwise, the popup will be in undesired position.
var expanded by remember { mutableStateOf(false) } val suggestions = listOf("Item1", "Item2", "Item3") Box { Button(onClick = { expanded = !expanded }){ Text ("DropDown") Icon( imageVector = Icons.Filled.ArrowDropDown, contentDescription = null, ) } DropdownMenu( expanded = expanded, onDismissRequest = { expanded = false }, ) { suggestions.forEach { label -> DropdownMenuItem(onClick = { expanded = false //do something ... }) { Text(text = label) } } } }
