Installation

caveui components are copy-paste Jetpack Compose built entirely on Material 3 — there's no caveui dependency to add. Make sure Material 3 is on your classpath (it ships with the Compose BOM), then copy the Usage snippet below into your project.

kotlin

// build.gradle.kts (module)
dependencies {
    implementation(platform("androidx.compose:compose-bom:2025.06.00"))
    implementation("androidx.compose.material3:material3")
}

Usage

kotlin

@Composable
fun SplitButton() {
    var open by remember { mutableStateOf(false) }
    Row {
        Button(
            onClick = {},
            shape = RoundedCornerShape(
                topStart = 50f, bottomStart = 50f,
                topEnd = 0f, bottomEnd = 0f,
            ),
        ) { Text("Save") }
        Box {
            Button(
                onClick = { open = true },
                shape = RoundedCornerShape(
                    topStart = 0f, bottomStart = 0f,
                    topEnd = 50f, bottomEnd = 50f,
                ),
                contentPadding = PaddingValues(horizontal = 8.dp),
            ) { Icon(Icons.Filled.ArrowDropDown, "More") }
            DropdownMenu(expanded = open, onDismissRequest = { open = false }) {
