New Compose Multiplatform components arrived on Composables UICheck it out →


Checkboxes can have a parent-child relationship with other checkboxes. When the parent checkbox is checked, all child checkboxes are checked. If a parent checkbox is unchecked, all child checkboxes are unchecked. If some, but not all, child checkboxes are checked, the parent checkbox becomes an indeterminate checkbox.

statewhether TriStateCheckbox is checked, unchecked or in indeterminate state
onClickcallback to be invoked when checkbox is being clicked, therefore the change of ToggleableState state is requested. If null, then this is passive and relies entirely on a higher-level component to control the state.
modifierModifier to be applied to the layout of the checkbox
enabledwhether the component is enabled or grayed out
interactionSourcean optional hoisted [MutableInteractionSource] for observing and emitting [Interaction]s for this checkbox. You can use this to change the checkbox's appearance or preview the checkbox in different states. Note that if null is provided, interactions will still happen internally.
colors[CheckboxColors] that will be used to determine the color of the checkmark / box / border in different states. See [CheckboxDefaults.colors].

Code Example


fun TriStateCheckboxSample() {
    Column {
        // define dependent checkboxes states
        val (state, onStateChange) = remember { mutableStateOf(true) }
        val (state2, onStateChange2) = remember { mutableStateOf(true) }

        // TriStateCheckbox state reflects state of dependent checkboxes
        val parentState = remember(state, state2) {
            if (state && state2) ToggleableState.On
            else if (!state && !state2) ToggleableState.Off
            else ToggleableState.Indeterminate
        // click on TriStateCheckbox can set state for dependent checkboxes
        val onParentClick = {
            val s = parentState != ToggleableState.On

            state = parentState,
            onClick = onParentClick,
            colors = CheckboxDefaults.colors(
                checkedColor = MaterialTheme.colors.primary
        Column(Modifier.padding(10.dp, 0.dp, 0.dp, 0.dp)) {
            Checkbox(state, onStateChange)
            Checkbox(state2, onStateChange2)
