Menu drop-down memungkinkan pengguna mengklik ikon, kolom teks, atau komponen lain, lalu memilih dari daftar opsi di permukaan sementara. Panduan ini menjelaskan cara membuat menu dasar dan menu yang lebih kompleks dengan pemisah dan ikon.

Platform API
Gunakan komponen DropdownMenu, DropdownMenuItem, dan IconButton
untuk menerapkan menu drop-down kustom. Komponen DropdownMenu dan
DropdownMenuItem digunakan untuk menampilkan item menu, sedangkan
IconButton adalah pemicu untuk menampilkan atau menyembunyikan menu drop-down.
Parameter utama untuk komponen DropdownMenu meliputi:
expanded: Menunjukkan apakah menu terlihat.
onDismissRequest: Digunakan untuk menangani penutupan menu.
content: Konten composable menu, biasanya berisi
composable DropdownMenuItem.
Parameter utama untuk DropdownMenuItem meliputi hal berikut:
text: Menentukan konten yang ditampilkan di item menu.
onClick: Callback untuk menangani interaksi dengan item di menu.
Membuat menu drop-down dasar
Cuplikan berikut menunjukkan implementasi DropdownMenu minimal:
@ComposablefunMinimalDropdownMenu(){varexpandedbyremember{mutableStateOf(false)}Box(modifier=Modifier.padding(16.dp)){IconButton(onClick={expanded=!expanded}){Icon(Icons.Default.MoreVert,contentDescription="More options")}DropdownMenu(expanded=expanded,onDismissRequest={expanded=false}){DropdownMenuItem(text={Text("Option 1")},onClick={/* Do something... */})DropdownMenuItem(text={Text("Option 2")},onClick={/* Do something... */})}}}
Mendefinisikan DropdownMenu dasar yang berisi dua item menu.
Parameter expanded mengontrol visibilitas menu sebagai diperluas atau diciutkan.
Parameter onDismissRequest menentukan callback yang dieksekusi saat
pengguna menutup menu.
Composable DropdownMenuItem merepresentasikan item yang dapat dipilih di menu drop-down.
IconButton memicu perluasan dan penciutan menu.
Hasil
Gambar 2. Menu drop-down minimal dengan hanya dua opsi.
Membuat menu dropdown yang lebih panjang
DropdownMenu dapat di-scroll secara default jika semua item menu tidak dapat ditampilkan
sekaligus. Cuplikan berikut membuat menu drop-down yang lebih panjang dan dapat di-scroll:
@ComposablefunLongBasicDropdownMenu(){varexpandedbyremember{mutableStateOf(false)}// Placeholder list of 100 strings for demonstrationvalmenuItemData=List(100){"Option ${it+1}"}Box(modifier=Modifier.padding(16.dp)){IconButton(onClick={expanded=!expanded}){Icon(Icons.Default.MoreVert,contentDescription="More options")}DropdownMenu(expanded=expanded,onDismissRequest={expanded=false}){menuItemData.forEach{option->
DropdownMenuItem(text={Text(option)},onClick={/* Do something... */})}}}}
DropdownMenu dapat di-scroll jika total tinggi kontennya melebihi ruang yang tersedia. Kode ini membuat DropdownMenu yang dapat di-scroll
yang menampilkan 100 item placeholder.
Loop forEach membuat composable DropdownMenuItem secara dinamis. Item tidak dibuat secara lambat, yang berarti semua 100 item drop-down dibuat dan ada dalam komposisi.
IconButton memicu peluasan dan penciutan DropdownMenu
saat diklik.
Lambda onClick dalam setiap DropdownMenuItem memungkinkan Anda menentukan
tindakan yang dilakukan saat pengguna memilih item menu.
Hasil
Cuplikan kode sebelumnya menghasilkan menu yang dapat di-scroll berikut:

Membuat menu drop-down yang lebih panjang dengan pemisah
Cuplikan berikut menunjukkan implementasi menu drop-down yang lebih canggih.
Dalam cuplikan ini, ikon di awal dan akhir ditambahkan ke item menu, dan
pemisah memisahkan grup item menu.
@ComposablefunDropdownMenuWithDetails(){varexpandedbyremember{mutableStateOf(false)}Box(modifier=Modifier.fillMaxWidth().padding(16.dp)){IconButton(onClick={expanded=!expanded}){Icon(Icons.Default.MoreVert,contentDescription="More options")}DropdownMenu(expanded=expanded,onDismissRequest={expanded=false}){// First sectionDropdownMenuItem(text={Text("Profile")},leadingIcon={Icon(Icons.Outlined.Person,contentDescription=null)},onClick={/* Do something... */})DropdownMenuItem(text={Text("Settings")},leadingIcon={Icon(Icons.Outlined.Settings,contentDescription=null)},onClick={/* Do something... */})HorizontalDivider()// Second sectionDropdownMenuItem(text={Text("Send Feedback")},leadingIcon={Icon(Icons.Outlined.Feedback,contentDescription=null)},trailingIcon={Icon(Icons.AutoMirrored.Outlined.Send,contentDescription=null)},onClick={/* Do something... */})HorizontalDivider()// Third sectionDropdownMenuItem(text={Text("About")},leadingIcon={Icon(Icons.Outlined.Info,contentDescription=null)},onClick={/* Do something... */})DropdownMenuItem(text={Text("Help")},leadingIcon={Icon(Icons.AutoMirrored.Outlined.Help,contentDescription=null)},trailingIcon={Icon(Icons.AutoMirrored.Outlined.OpenInNew,contentDescription=null)},onClick={/* Do something... */})}}}

This guide describes\nhow to create both basic menus and more complex menus with dividers and icons.\n**Figure 1.** A basic drop-down menu with two items listed.\n\nAPI surface\n\nUse [`DropdownMenu`](/reference/kotlin/androidx/compose/material3/package-summary#DropdownMenu(kotlin.Boolean,kotlin.Function0,androidx.compose.ui.Modifier,androidx.compose.ui.unit.DpOffset,androidx.compose.foundation.ScrollState,androidx.compose.ui.window.PopupProperties,androidx.compose.ui.graphics.Shape,androidx.compose.ui.graphics.Color,androidx.compose.ui.unit.Dp,androidx.compose.ui.unit.Dp,androidx.compose.foundation.BorderStroke,kotlin.Function1)), [`DropdownMenuItem`](/reference/kotlin/androidx/compose/material3/package-summary#DropdownMenuItem(kotlin.Function0,kotlin.Function0,androidx.compose.ui.Modifier,kotlin.Function0,kotlin.Function0,kotlin.Boolean,androidx.compose.material3.MenuItemColors,androidx.compose.foundation.layout.PaddingValues,androidx.compose.foundation.interaction.MutableInteractionSource)), and the [`IconButton`](/reference/kotlin/androidx/compose/material3/package-summary#IconButton(kotlin.Function0,androidx.compose.ui.Modifier,kotlin.Boolean,androidx.compose.material3.IconButtonColors,androidx.compose.foundation.interaction.MutableInteractionSource,androidx.compose.ui.graphics.Shape,kotlin.Function0))\ncomponents to implement a custom drop-down menu. The `DropdownMenu` and\n`DropdownMenuItem` components are used to display the menu items, while the\n`IconButton` is the trigger to display or hide the drop-down menu.\n\nThe key parameters for the `DropdownMenu` component include the following:\n\n- `expanded`: Indicates whether the menu is visible.\n- `onDismissRequest`: Used to handle menu dismissal.\n- `content`: The composable content of the menu, typically containing `DropdownMenuItem` composables.\n\nThe key parameters for `DropdownMenuItem` include the following:\n\n- `text`: Defines the content displayed in the menu item.\n- `onClick`: Callback to handle interaction with the item in the menu.\n\nCreate a basic drop-down menu\n\nThe following snippet demonstrates a minimal `DropdownMenu` implementation:\n\n\n```kotlin\n@Composable\nfun MinimalDropdownMenu() {\n var expanded by remember { mutableStateOf(false) }\n Box(\n modifier = Modifier\n .padding(16.dp)\n ) {\n IconButton(onClick = { expanded = !expanded }) {\n Icon(Icons.Default.MoreVert, contentDescription = \"More options\")\n }\n DropdownMenu(\n expanded = expanded,\n onDismissRequest = { expanded = false }\n ) {\n DropdownMenuItem(\n text = { Text(\"Option 1\") },\n onClick = { /* Do something... */ }\n )\n DropdownMenuItem(\n text = { Text(\"Option 2\") },\n onClick = { /* Do something... */ }\n )\n }\n }\n}https://github.com/android/snippets/blob/7a0ebbee11495f628cf9d574f6b6069c2867232a/compose/snippets/src/main/java/com/example/compose/snippets/components/Menus.kt#L98-L122\n```\n\n\u003cbr /\u003e\n\nKey points about the code\n\n- Defines a basic `DropdownMenu` containing two menu items.\n- The `expanded` parameter controls the menu's visibility as expanded or collapsed.\n- The `onDismissRequest` parameter defines a callback that executes when the user closes the menu.\n- The `DropdownMenuItem` composable represents selectable items in the drop-down menu.\n- An `IconButton` triggers the expansion and collapse of the menu.\n\nResult **Figure 2.** A minimal drop-down menu with only two options.\n\nCreate a longer drop-down menu\n\n`DropdownMenu` is scrollable by default if all the menu items can't be displayed\nat once. The following snippet creates a longer, scrollable drop-down menu:\n\n\n```kotlin\n@Composable\nfun LongBasicDropdownMenu() {\n var expanded by remember { mutableStateOf(false) }\n // Placeholder list of 100 strings for demonstration\n val menuItemData = List(100) { \"Option ${it + 1}\" }\n\n Box(\n modifier = Modifier\n .padding(16.dp)\n ) {\n IconButton(onClick = { expanded = !expanded }) {\n Icon(Icons.Default.MoreVert, contentDescription = \"More options\")\n }\n DropdownMenu(\n expanded = expanded,\n onDismissRequest = { expanded = false }\n ) {\n menuItemData.forEach { option -\u003e\n DropdownMenuItem(\n text = { Text(option) },\n onClick = { /* Do something... */ }\n )\n }\n }\n }\n}https://github.com/android/snippets/blob/7a0ebbee11495f628cf9d574f6b6069c2867232a/compose/snippets/src/main/java/com/example/compose/snippets/components/Menus.kt#L132-L157\n```\n\n\u003cbr /\u003e\n\nKey points about the code\n\n- The `DropdownMenu` is scrollable when the total height of its content exceeds the available space. This code creates a scrollable `DropdownMenu` that displays 100 placeholder items.\n- The `forEach` loop dynamically generates `DropdownMenuItem` composables. The items are not lazily created, which means that all 100 drop-down items are created and exist in the composition.\n- The `IconButton` triggers the expansion and collapse of the `DropdownMenu` when clicked.\n- The `onClick` lambda within each `DropdownMenuItem` lets you define the action performed when the user selects a menu item.\n\nResult\n\nThe preceding code snippet produces the following scrollable menu:\n**Figure 3.** A long, scrollable drop-down menu.\n\nCreate a longer drop-down menu with dividers\n\nThe following snippet shows a more advanced implementation of a drop-down menu.\nIn this snippet, leading and trailing icons are added to menu items, and\ndividers separate groups of menu items.\n\n\n```kotlin\n@Composable\nfun DropdownMenuWithDetails() {\n var expanded by remember { mutableStateOf(false) }\n\n Box(\n modifier = Modifier\n .fillMaxWidth()\n .padding(16.dp)\n ) {\n IconButton(onClick = { expanded = !expanded }) {\n Icon(Icons.Default.MoreVert, contentDescription = \"More options\")\n }\n DropdownMenu(\n expanded = expanded,\n onDismissRequest = { expanded = false }\n ) {\n // First section\n DropdownMenuItem(\n text = { Text(\"Profile\") },\n leadingIcon = { Icon(Icons.Outlined.Person, contentDescription = null) },\n onClick = { /* Do something... */ }\n )\n DropdownMenuItem(\n text = { Text(\"Settings\") },\n leadingIcon = { Icon(Icons.Outlined.Settings, contentDescription = null) },\n onClick = { /* Do something... */ }\n )\n\n HorizontalDivider()\n\n // Second section\n DropdownMenuItem(\n text = { Text(\"Send Feedback\") },\n leadingIcon = { Icon(Icons.Outlined.Feedback, contentDescription = null) },\n trailingIcon = { Icon(Icons.AutoMirrored.Outlined.Send, contentDescription = null) },\n onClick = { /* Do something... */ }\n )\n\n HorizontalDivider()\n\n // Third section\n DropdownMenuItem(\n text = { Text(\"About\") },\n leadingIcon = { Icon(Icons.Outlined.Info, contentDescription = null) },\n onClick = { /* Do something... */ }\n )\n DropdownMenuItem(\n text = { Text(\"Help\") },\n leadingIcon = { Icon(Icons.AutoMirrored.Outlined.Help, contentDescription = null) },\n trailingIcon = { Icon(Icons.AutoMirrored.Outlined.OpenInNew, contentDescription = null) },\n onClick = { /* Do something... */ }\n )\n }\n }\n}https://github.com/android/snippets/blob/7a0ebbee11495f628cf9d574f6b6069c2867232a/compose/snippets/src/main/java/com/example/compose/snippets/components/Menus.kt#L167-L221\n```\n\n\u003cbr /\u003e\n\nThis code defines a `DropdownMenu` within a `Box`.\n\nKey points about the code\n\n- The `leadingIcon` and `trailingIcon` parameters add icons to the start and end of a `DropdownMenuItem`.\n- An `IconButton` triggers the menu's expansion.\n- The `DropdownMenu` contains several `DropdownMenuItem` composables, each representing a selectable action.\n- [`HorizontalDivider`](/reference/kotlin/androidx/compose/material3/package-summary#HorizontalDivider(androidx.compose.ui.Modifier,androidx.compose.ui.unit.Dp,androidx.compose.ui.graphics.Color)) composables insert a horizontal line to separate groups of menu items.\n\nResult\n\nThe preceding snippet produces a drop-down menu with icons and dividers:\n**Figure 4.** A drop-down menu divided into sections with leading and trailing icons.\n\nAdditional resources\n\n- Material Design: [Menus](https://m3.material.io/components/menus)"]]
