Select Seat

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 SeatMapCard() {
  var sel by remember { mutableStateOf(-1) }
  Card(modifier = Modifier.fillMaxWidth().padding(16.dp)) {
    Column(Modifier.padding(20.dp)) {
      Text("Select Seat",
        style = MaterialTheme.typography.titleMedium)
      Spacer(Modifier.height(12.dp))
      repeat(3) { row ->
        Row(
          Modifier.fillMaxWidth(),
          horizontalArrangement = Arrangement.SpaceEvenly
        ) {
          repeat(4) { col ->
            val idx = row * 4 + col
            val on = sel == idx
            val sc by animateFloatAsState(
              if (on) 1.2f else 1f, label = "s"
            )
            Box(
              Modifier.padding(4.dp).size(28.dp)
                .graphicsLayer { scaleX = sc; scaleY = sc }
                .background(
                  if (on) Color(0xFF6366F1)
                    else Color.Gray.copy(0.25f),
                  RoundedCornerShape(6.dp)
                ).clickable { sel = idx }
            )
          }
