InputChip

Component in Material 3 Compose

Chips help people enter information, make selections, filter content, or trigger actions. Chips can show multiple interactive elements together in the same area, such as a list of selectable movie times, or a series of email contacts.

Input chips represent discrete pieces of information entered by a user.

Overloads

@Composable
fun InputChip(
    selected: Boolean,
    onClick: () -> Unit,
    label: @Composable () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    leadingIcon: @Composable (() -> Unit)? = null,
    avatar: @Composable (() -> Unit)? = null,
    trailingIcon: @Composable (() -> Unit)? = null,
    shape: Shape = InputChipDefaults.shape,
    colors: SelectableChipColors = InputChipDefaults.inputChipColors(),
    elevation: SelectableChipElevation? = InputChipDefaults.inputChipElevation(),
    border: BorderStroke? = InputChipDefaults.inputChipBorder(enabled, selected),
    interactionSource: MutableInteractionSource? = null,
)

Parameters

name	description
selected	whether this chip is selected or not
onClick	called when this chip is clicked
label	text label for this chip
modifier	the [Modifier] to be applied to this chip
enabled	controls the enabled state of this chip. When false, this component will not respond to user input, and it will appear visually disabled and disabled to accessibility services.
leadingIcon	optional icon at the start of the chip, preceding the [label] text
avatar	optional avatar at the start of the chip, preceding the [label] text
trailingIcon	optional icon at the end of the chip
shape	defines the shape of this chip's container, border (when [border] is not null), and shadow (when using [elevation])
colors	[ChipColors] that will be used to resolve the colors used for this chip in different states. See [InputChipDefaults.inputChipColors].
elevation	[ChipElevation] used to resolve the elevation for this chip in different states. This controls the size of the shadow below the chip. Additionally, when the container color is [ColorScheme.surface], this controls the amount of primary color applied as an overlay. See [InputChipDefaults.inputChipElevation].
border	the border to draw around the container of this chip. Pass null for no border. See [InputChipDefaults.inputChipBorder].
interactionSource	an optional hoisted [MutableInteractionSource] for observing and emitting [Interaction]s for this chip. You can use this to change the chip's appearance or preview the chip in different states. Note that if null is provided, interactions will still happen internally.
