Bottom sheet picker

A field that opens a modal bottom sheet listing options with a checked state.

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 SheetSelect(options: List<String>) {
    var open by remember { mutableStateOf(false) }
    var selected by remember { mutableStateOf(options.first()) }
    OutlinedTextField(
        value = selected, onValueChange = {}, readOnly = true,
        label = { Text("Category") },
        trailingIcon = { Icon(Icons.Filled.ExpandMore, null) },
        modifier = Modifier.fillMaxWidth().clickable { open = true },
    )
    if (open) {
        ModalBottomSheet(onDismissRequest = { open = false }) {
            options.forEach { o ->
                ListItem(
                    headlineContent = { Text(o) },
                    trailingContent = {
                        if (o == selected) Icon(Icons.Filled.Check, null,
                            tint = MaterialTheme.colorScheme.primary)
                    },
                    modifier = Modifier.clickable { selected = o; open = false },
                )
            }
        }
    }
}
