ToggleButtonGroup

A ToggleButtonGroup is a group of ToggleButtons that allows users to select one or multiple buttons from the group.

Guidelines

Using toggle button groups

Buttons within the toggle button group must carry a label. In the case of icon-only buttons, the label will be available only to screen reader users.

Use the ToggleButtonGroup when you require users to select either one or multiple options from a group. If you want users to choose from a set of actions, with the restriction that only one can be active simultaneously, use the ButtonGroup instead.

Specifications

A toggle button group consists of normal (framed) buttons, which may include the following elements:

Icon (optional)
Icons simplify user recognition and provide the ability to shorten button labels to a minimum.
Label
Button labels should be as short as possible, with text that clearly states what option will be selected when the button is toggled on.
White line
For toggled-on buttons, a white line is added to visually separate them, whether they are on the same line or placed on different rows in the stacked version.

Refer to the ToggleButtonGroup component in Codex Figma.

Stacked buttons

When the ToggleButtonGroup exceeds the available space on a single line, the buttons will wrap onto the next line.

Interaction states

ToggleButtonGroups have the following visually separate states:

Default
Hover on one button
Active button
Focus on one button
One button is selected
One button is disabled
Hover on the selected button
The selected button is active
Focus on the selected button
Two buttons are selected
All buttons are selected
All buttons are disabled

Demos

Single value

To allow only a single value to be selected, initialize v-model to null.

Selected value: (null)

Name	Value
View
Reading direction	Left to right (LTR) Right to left (RTL)

Initially selected single value

To start with one button already selected, initialize v-model to that value.

Use the icon property to add an icon before the text of a button. Use the disabled property to disable individual buttons. For more information on how to control the appearance of each button, see the ButtonGroup documentation.

Selected value: framed

		// Initially select the 'Framed' button
		const selectedValue = ref( 'framed' );

		return {
			buttons,
			selectedValue
		};
	}
} );
</script>

Multiple values

To allow multiple values to be selected, initialize v-model to an empty array ([]). To start with some of buttons already selected, initialize v-model to an array of the values of those buttons.

Selected values: (none)

Disabled

The entire component can be disabled by setting the disabled prop. Individual buttons can be disabled by setting their .disabled property.

Overflowing buttons

When the button group is too large to fit on one line, the buttons overflow to the next line.

Selected values: (none)

Custom button display

The contents of the buttons can be customized using the default slot. The ButtonGroupItem object for each button is available through the button binding, and the selected state of each button is available through the selected binding. In this example, the value of the button is displayed after its label, but only if the button is selected.

Selected value: 2

Vue usage

Whether the group is single-select or multi-select is automatically detected based on the value bound to v-model: if it's an array, the group allows multiple selections; otherwise, it only allows a single selection. To initially select nothing, initialize the v-model value to null (for single-select groups) or [] (for multi-select groups).

Props

Prop name	Description	Type	Default
`buttons`^(required)	Buttons to display. See the ButtonGroupItem type.	`ButtonGroupItem[]`
`modelValue`^(required)	Selected value, or array of selected values. If this is a string or number, the button whose value equals that string or number is selected, and only a single selection is allowed. If this is an array, the buttons whose values equal any of the values in the array are selected, and multiple selections are allowed. To select none of the buttons initially, set this to `null` (for single-selection groups) or to `[]` (for multi-selection groups). Must be bound with `v-model`.	`string\|number\|null\|( string\|number )[]`
`disabled`	Whether the entire group is disabled. If this is set to true, all buttons in the group are disabled. Buttons can also be disabled individually by setting their `disabled` property to true.	`boolean`	`false`

Events
