Usage

import { TopicTags, TopicTag } from '@bbc/psammead-topic-tags';
import { latin } from '@bbc/gel-foundations/scripts';

const Wrapper = () => (
  <TopicTags script={latin} service="news" dir="ltr">
    <TopicTag topicName="Retailing" topicLink="/url/to/topic" />
    <TopicTag topicName="Business" topicLink="/url/to/topic" />
    <TopicTag topicName="Viruses" topicLink="/url/to/topic" />
  </TopicTags>
);

When to use this component

The TopicTag component should only be used inside of a TopicTags component, and a TopicTags component should only be used to contain TopicTag components.

Accessibility notes

The TopicTags component is fundamentally a <ul> when there is more than 1 TopicTag, and the <ul> uses the ARIA role="list" attribute. This reinstates the list semantics on VoiceOver which removes them due to the use of list-style-type: none; in the CSS.
