The sbb-tag is a component that can be used as a filter in order to categorize a large amount of information.
It's intended to be used inside an <sbb-tag-group>.
It is possible to provide a label via an unnamed slot; the component can optionally display a <sbb-icon>
at the component start using the iconName property or via custom content using the icon slot.
It's also possible to display a numeric amount at the component's end using the amount slot.
Consumers can listen to the native change and input events on the <sbb-tag>.
The current state can be read from event.target.checked, while the value from event.target.value.
It's recommended to check the parent's <sbb-tag-group> for the value.
Usage
Checked:
<sbb-tag checked value="All" amount="123">All</sbb-tag>Unchecked disabled with icon:
<sbb-tag disabled value="All" icon-name="circle-information-small">All</sbb-tag>Unchecked required with custom icon and amount:
<sbb-tag value="All">
<sbb-icon slot="icon" name="pie-small" />
All
<span slot="amount">123</span>
</sbb-tag>Accessibility
The component imitates an <button> element to provide an accessible experience.
The state is reflected via aria-pressed attribute.
