CodexButtonGroup
A set of two or more buttons representing related actions.
Buttons in this button group signal a number of equally important actions that will occur when the user taps on them. Button groups feature a set of normal buttons that can include icons and/or text labels.
Demos
Open up the browser console to see events emitted on click.
Basic usage
Describe the buttons in the group with an array of ButtonGroupItem objects. The text in the label property will be displayed in the buttons. When a button is clicked, a click event will be emitted with the value property of the clicked button. Values must be unique within a button group.
If the label property is omitted, the value property will be used as the label. This allows using { value: 'Foo' } as a shorthand for { label: 'Foo', value: 'Foo' }.

With icons
Use the icon property to add an icon before the text of a button. Use the disabled property to disable individual buttons.
<template>
<cdx-button-group
:buttons="buttons"
@click="onClick"
/>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import { CdxButtonGroup, ButtonGroupItem } from '@wikimedia/codex';
import { cdxIconEdit, cdxIconSpeechBubble, cdxIconCheck, cdxIconDownload, cdxIconTrash } from '@wikimedia/codex-icons';
import getEventLogger from '../../../src/utils/getEventLogger';
export default defineComponent( {
name: 'ButtonGroupWithIcons',
components: {
CdxButtonGroup
},
setup() {
const buttons: ButtonGroupItem[] = [
{ value: 'edit', label: 'Edit', icon: cdxIconEdit },
{ value: 'talk', label: 'Discuss', icon: cdxIconSpeechBubble },
{ value: 'save', label: 'Done', icon: cdxIconCheck, disabled: true },
{ value: 'download', label: 'Download', icon: cdxIconDownload, disabled: true },
{ value: 'delete', label: 'Delete', icon: cdxIconTrash }
];
const onClick = getEventLogger<string|number>( 'click' );
return {
buttons,
onClick
};
}
} );
</script>Icon-only buttons
To display an icon as the only content of a button, use the icon property to specify an icon, and set the label property to null.
<template>
<cdx-button-group
:buttons="buttons"
@click="onClick"
/>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import { CdxButtonGroup, ButtonGroupItem } from '@wikimedia/codex';
import { cdxIconEdit, cdxIconSpeechBubble, cdxIconCheck, cdxIconDownload, cdxIconTrash } from '@wikimedia/codex-icons';
import getEventLogger from '../../../src/utils/getEventLogger';
export default defineComponent( {
name: 'IconOnlyButtonGroup',
components: {
CdxButtonGroup
},
setup() {
const buttons: ButtonGroupItem[] = [
{ value: 'edit', label: null, icon: cdxIconEdit, ariaLabel: 'Edit' },
{ value: 'talk', label: null, icon: cdxIconSpeechBubble, ariaLabel: 'Discuss' },
{ value: 'save', label: null, icon: cdxIconCheck, ariaLabel: 'Done', disabled: true },
{ value: 'download', label: null, icon: cdxIconDownload, ariaLabel: 'Download', disabled: true },
{ value: 'delete', label: null, icon: cdxIconTrash, ariaLabel: 'Delete' }
];
const onClick = getEventLogger<string|number>( 'click' );
return {
buttons,
onClick
};
}
} );
</script>Disabled
The entire component can be disabled by setting the disabled prop. Individual buttons can be disabled by setting their .disabled property. Clicking a disabled button does not emit a click event.
<template>
<cdx-button-group
:buttons="buttons"
:disabled="true"
@click="onClick"
/>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import { CdxButtonGroup, ButtonGroupItem } from '@wikimedia/codex';
import getEventLogger from '../../../src/utils/getEventLogger';
export default defineComponent( {
name: 'DisabledButtonGroup',
components: {
CdxButtonGroup
},
setup() {
const buttons: ButtonGroupItem[] = [
{ value: 1, label: 'One' },
{ value: 2, label: 'Two' },
{ value: 3, label: 'Three' },
{ value: 4, label: 'Four', disabled: true },
{ value: 5, label: 'Five' }
];
const onClick = getEventLogger<string|number>( 'click' );
return {
buttons,
onClick
};
}
} );
</script>Overflowing buttons
When the button group is too large to fit on one line, the buttons overflow to the next line.
<template>
<cdx-button-group
:buttons="buttons"
@click="onClick"
/>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import { CdxButtonGroup, ButtonGroupItem } from '@wikimedia/codex';
import getEventLogger from '../../../src/utils/getEventLogger';
export default defineComponent( {
name: 'MaximumButtonGroup',
components: {
CdxButtonGroup
},
setup() {
const buttons: ButtonGroupItem[] = [
{ value: 1, label: 'First button' },
{ value: 2, label: 'Second button' },
{ value: 3, label: 'Third button with a long label' },
{ value: 4, label: 'Fourth button with a long label' },
{ value: 5, label: 'Fifth button' }
];
const onClick = getEventLogger<string|number>( 'click' );
return {
buttons,
onClick
};
}
} );
</script>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. In this example, the value of the button is displayed in superscript after its label.
<template>
<cdx-button-group
:buttons="buttons"
@click="onClick"
>
<template #default="{ button }">
{{ button.label }}
<sup>
({{ button.value }})
</sup>
</template>
</cdx-button-group>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import { CdxButtonGroup, ButtonGroupItem } from '@wikimedia/codex';
import getEventLogger from '../../../src/utils/getEventLogger';
export default defineComponent( {
name: 'ButtonGroupWithSlot',
components: {
CdxButtonGroup
},
setup() {
const buttons: ButtonGroupItem[] = [
{ value: 1, label: 'One' },
{ value: 2, label: 'Two' }
];
const onClick = getEventLogger<string|number>( 'click' );
return {
buttons,

};

} );
