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

@OptIn(ExperimentalMaterial3Api::class)
@Composable
fun CountrySelect(options: List<String>) {
    var expanded by remember { mutableStateOf(false) }
    var selected by remember { mutableStateOf(options.first()) }
    ExposedDropdownMenuBox(
        expanded = expanded,
        onExpandedChange = { expanded = it },
    ) {
        OutlinedTextField(
            value = selected,
            onValueChange = {},
            readOnly = true,
            label = { Text("Country") },
            trailingIcon = {
                ExposedDropdownMenuDefaults.TrailingIcon(expanded = expanded)
            },
            modifier = Modifier.menuAnchor().fillMaxWidth(),
        )
        ExposedDropdownMenu(
            expanded = expanded,
            onDismissRequest = { expanded = false },
        ) {
            options.forEach { option ->
                DropdownMenuItem(
                    text = { Text(option) },
                    onClick = {
                        selected = option
                        expanded = false
