Rich textarea

Multiline composer topped by a formatting toolbar in a single bordered surface.

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

var value by remember { mutableStateOf("") }
Column(
    Modifier.border(
        1.dp, MaterialTheme.colorScheme.outline,
        MaterialTheme.shapes.medium,
    ),
) {
    Row(Modifier.padding(4.dp)) {
        listOf("B", "I", "U").forEach {
            TextButton(onClick = {}) {
                Text(it, fontWeight = FontWeight.Bold)
            }
        }
    }
    HorizontalDivider()
    BasicTextField(
        value = value,
        onValueChange = { value = it },
