# Citation – Code

> The Citation provides a pill-styled link to a source for agent-generated content.

  <Tab title="Implementation">
    <LiveCode showCode example="ai-kit-citation" fullWidth screenshot>
      ```tsx lines expandable theme={null}
      import { Citation } from "@servicetitan/anvil2-ai-kit";

      function App() {
        return <Citation href="https://example.com" text="Source" />;
      }

      export default App;
      ```
    </LiveCode>

    ## Common Examples

    To use the `Citation`, import it from `@servicetitan/anvil2-ai-kit` and pass the required `href` and `text` props. Use an on-page anchor for a source list or an external URL for the original source.

    ```tsx theme={null}
    import { Citation } from "@servicetitan/anvil2-ai-kit";

    function ExampleComponent() {
      return <Citation href="#sources" text="Source 1" />;
    }
    ```

    ### New tab

    Set `target="_blank"` for an external source. `Citation` appends an open-in-new icon, defaults `rel` to `"noopener noreferrer"` unless you pass `rel`, and announces "(opens in a new tab)" to assistive technology.

    <LiveCode showCode example="ai-kit-citation-open-in-new" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { Citation } from "@servicetitan/anvil2-ai-kit";

      function App() {
        return (
          <div style={{ display: "flex", gap: 12 }}>
            {/* Opens in a new tab */}
            <Citation href="https://example.com" text="Source" target="_blank" />

            {/* Stays on the page */}
            <Citation href="#sources" text="On-page source" />
          </div>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### Inline in text

    `Citation` renders inline and does not split across lines, so it can identify a source without interrupting the surrounding copy.

    <LiveCode showCode example="ai-kit-citation-inline" screenshot fullWidth>
      ```tsx lines expandable theme={null}
      import { Citation, Text } from "@servicetitan/anvil2-ai-kit";

      function App() {
        return (
          <div style={{ maxWidth: "28rem" }}>
            <Text
              text={
                <>
                  The customer's account is in good standing with no overdue balances{" "}
                  <Citation href="https://example.com" text="Source" />.
                </>
              }
            />
          </div>
        );
      }

      export default App;
      ```
    </LiveCode>

    ## Internationalization

    `Citation` uses the `ai-kit.citation.opensInNewTab` message for the new-tab announcement. English is the default. Mount `AiKitIntlProvider` inside `CartoTheme` to switch locale or override the string.

    ```tsx theme={null}
    import {
      AiKitIntlProvider,
      CartoTheme,
      Citation,
    } from "@servicetitan/anvil2-ai-kit";

    function Root() {
      return (
        <CartoTheme>
          <AiKitIntlProvider
            locale="fr-FR"
            messages={{
              "ai-kit.citation.opensInNewTab":
                "(s'ouvre dans un nouvel onglet)",
            }}
          >
            <Citation
              href="https://example.com/report"
              target="_blank"
              text="Source"
            />
          </AiKitIntlProvider>
        </CartoTheme>
      );
    }
    ```

    ## React Accessibility

    * `text` is the visible link text and accessible name.
    * `target="_blank"` adds a localized new-tab announcement and a trailing icon.
    * Users activate a focused citation with Enter.
  </Tab>

  <Tab title="Citation Props">
    ```tsx theme={null}
    <Citation href="#sources" text="Source 1" />
    ```

    ## `Citation` Props

    The `Citation` accepts the following props. It also forwards remaining React Aria `Link` props except `children`, `className`, `style`, and `href`.

    <ParamField path="href" type="string" required>
      Destination. Use an on-page anchor or an external URL.
    </ParamField>

    <ParamField path="text" type="string" required>
      Visible link text and accessible name.
    </ParamField>

    <ParamField path="className" type="string">
      Class merged onto the citation recipe class.
    </ParamField>

    <ParamField path="rel" type="string">
      Link relationship. When `target="_blank"` and `rel` is omitted or
      whitespace-only, `Citation` sets `"noopener noreferrer"`.
    </ParamField>

    <ParamField path="target" type="string">
      Anchor target. `"_blank"` adds the external-link treatment and localized
      announcement.
    </ParamField>
  </Tab>
