LazyDragSelectVerticalGrid
A wrapper for LazyVerticalGrid that provides drag selection functionality.
You can use LazyDragSelectGridItemScope.SelectableItem to wrap your item composable to make it selectable via a long press, or when selected via the drag-select.
Example usage:
@Composable
fun MyGrid() {
val items: List<Int> = List(100) { it }
val dragSelectState = rememberDragSelectState<Int>()
LazyDragSelectVerticalGrid(
columns = GridCells.Adaptive(minSize = 128.dp),
items = items,
state = dragSelectState,
verticalArrangement = Arrangement.spacedBy(3.dp),
horizontalArrangement = Arrangement.spacedBy(3.dp)
) {
items { item ->
// SelectableItem is available on the grid scope
SelectableItem(item = item) { selected ->
